Excavator repair: No Power, Stalling, Fuel tank and Filters. Yanmar ViO-50

My Yanmar has a problem where it loses power and then stalls. It's worse the higher the throttle is set. I've tried running it with the fuel cap off and that made no difference. Changing the inline fuel filter helps for a while, but then it happens again. What can I do to fix this thing?
Addressing some questions:
Why not use rust remover? Haven't heard of that before, and won't it just rust again? I didn't want to experiment only to find that I somehow made the problem worse. Are all rust removers compatible with diesel?
Magnets? Would certainly help, and I may do that if I continue to have problems. But they would require cleaning periodically. Would have to remove the side panel, and then the sending unit every time to clean. I could put a magnet on the side of the filters. I've never tried that before.
Why didn't I put the second tee in the other orientation so both filters have a 90 degree turn, equalizing the bias? Because I'm an idiot, that's why. I should have thought of that, and will do so. ;-)
What about electrolysis? Never thought of it. Cool idea, but it would also just rust again.
But you didn't really fix it. True, but that's the nature of owning and running machinery. You have to pick your battles, and choose where your time is best spent. To really fix this, I would have to remove the fuel tank and apply a tank lining product that should be a permanent fix. If it continues to plague me, I will probably do this at some point. But it would be many hours of work just to get that tank off.
Were those really sparks? Apparently some people think it was just light reflection. I don't think so myself, but I guess it's possible. I tried it twice more to see if I could repeat it and with the same camera and light setup, I didn't see the same result. I filmed sparks before, and that's exactly what they look like in freeze frame.

Excavator video this week. I'm still waiting on parts for the dump truck, but at this point I'm quite certain I have located everything I need. I HUGE thank you to all the people who reached out with suggestions and offers to help. Much appreciated! If you like the video, don't forget to give it a thumbs up, and check out my amazon store: www.amazon.com/shop/farmcraft101. Many of my favorite tools are listed there. Have an awesome weekend folks!

[@guytech7310]

Better option is a large filter similar in size as the main fuel filter, and perhaps a screen added to the replaceable filter to trap some of the larger debris. I would also consider flushing the tank with a some diesel & a small fuel pump into a bucket with a funnel to trap the debris. Let it run for an hour or two to get all of the loose debris out of the tank. Other wise your just burning $$$ buying replacement filters. You could also consider applying a Fuel tank sealer (KBS coatings). to seal off the rust & reduce contamination).

[@thorloki5449]

Wait isn't the state DOT supposed to take care of the "curb" to make sure it's a smooth transition. I no with most states that'd be like pulling teeth getting it done

[@jeffallen3382]

I've used the tank sealing kits on an old 72 Suzuki dirt bike. I bet if you poured some in and used your bloe gun to spread it around some. You would get a lot of the rusty floor covered.

[@prestonvandivier1379]

Just want to say i really appreciate the pacing and editing of your videos, keep up the good work, and the diversity of the content is excellent.

[@bosox6554]

What a pain in the Johnson.

[@danbarone7643]

I’m involved with experimental aircraft, one thing we learned about the pre filter you’re using is if the paper element gets water on it it will not pass fuel. You mentioned that you get condensation in the tank, if the water condensate makes it to that paper element in the filter it will act as though it is blocked. We don’t use them in aircraft for that reason. Something to think about.

[@ChrisMelancon]

I really don’t think those were sparks. It looked like droplets of fuel reflecting the light to me. With the camera looking into a dark tank a small reflection of light will appear overly bright. Also sparks would have illuminated the inside of the tank making everything noticeably brighter and that doesn’t appear to happen.

[@mlukegrady]

I agree, that's exactly what it looked like to me. If it were sparks it would have likely ignited that vaporized fuel.

[@Invinciblemoam]

Agreed, I came looking into the comments just for this

[@Watchyn_Yarwood]

👍

[@giggitygiggitygoofg6069]

It was defo RED dirty weasel diesel vaporising, with light shining through it made it kinda look like sparks but it was 100% not any kinda fire /ignition

[@BobJones-zf6ie]

...regardless I learned a lot from his speculation as well as this exchange concerning his speculation...thanks to you all.

[@3Hose]

I have an idea. Make (or maybe find) a canister filter housing and put removable neodymium magnets on the outside. Since this is rust it will stick to the sides of the canister where the magnets are and would be a quick easy clean out WITHOUT flow restriction issues. Once it is made it is a final solution with no more cost involved. Win, win.

[@shrike6259]

Yes UP vote.

[@chrismoffitt950]

Agreed, did this to a filthy landrover tank, worked a treat.

[@tweaker1968]

I was thinking just slap some magnets on the outside of the tank also...

[@hoyschelsilversteinberg4521]

[@Goalsplus]

That's pretty clever. I wonder why it isn't main stream. Maybe it's time for you to start manufacturing them or something.

[@ericl2152]

Idea, just put a second tank on the excavator and bypass the first. Quick, simple and effective. You could even cut the forward wall of the old tank you have access to and place a new plastic tank inside the old rusty tank. Then just utilize the existing fuel lines in place and the old fuel tank as a mounting bracket.

[@Pest789]

This is how people used to deal with broken TVs. They'd use the old dead console black and white TV as a stand for the svelte new color TV.

That's a prety hack job way to fix a tank that's really not that rusty. There are other ways to clean a tank and not have to take it out.

[@TheMoomba19]

I welded up a stainless steel fuel tank for my boat. It had to be of certain dimensions since it was going into the center console. I know I read in the comments about an additional or replacement tank being redneckish or a hacky way of doing things but honestly, I don't believe your main purpose is to win a beauty contest. I believe you just want to get some production out of a $20k+ piece of machinery you purchased. Life is short my friend and it shouldn't be full of drama and frustration. Get one built (or if you can TIG, do it yourself) and enjoy using what you purchased.

[@michaelovitch]

Phosphoric acid will remove rust only, without damaging the tank,just degrease the tank first. Filters can clog because of the fuel hoses degrading themselves from the inside,it's generally a black deposit. Check if the filtered material is magnetic or not. A big magnet can avoid rust to be sucked in the filter,stick it close,in front to the suction tube orifice.

[@Torbjorn.Lindgren]

Yeah, or any of the commercial rust converters which is usually tannic acid and/or phosphoric acid, plus various additives to make it work faster/better. And then use some kind of Epoxy Sealer which binds any remaining crud and stops any further problems - it'll probably outlast the rest of the vehicle.

[@aeros4me]

Put rags into the tank and blow them around using a high pressure air line. Clean / replace rags and continue until clean ;)

[@Watchyn_Yarwood]

@@aeros4me 👍 I have also used muriatic acid to clean rusty metal tanks.

[@Watchyn_Yarwood]

@@Torbjorn.Lindgren Absolutely! John has a tendency to over think when the solution could be much simpler.

[@dtroy15]

Most rust isn't magnetic. It depends on the oxide. A magnet lets most rust past.

[@Dysiode]

I know the "dumb farmer" trope is a complete farce, but still amazing to see the non-linear "maths" of how fuel filter lifespan works so intuitively explained. It's a real gift that you take time time to share all the complex work farmers have to do and reason through

[@duster.]

Thanks John. My wife and I have been binge watching your channel from the very first video. Thanks for the wonderful content and the humour, so much better than "traditional TV".

[@1945jlee]

Even diesel tanks condensate water out of the air inside the tank. Add red bottle HEET (Heet Iso-HEET Water Remover And Premium Fuel Line Antifreeze + Injector Cleaner) Helps to stop rust. That 2nd filter is a Sediment Filter(&water), heavies would drop to the bottom of the bowl, just remove bowl (when needed) clean and replace. The little filter will last a long time. Great videos Jon, I watch a lot!

[@dereksstuff8395]

Do yourself a favor and buy a neodymium magnet and leave it in the tank, near the outlet. Periodically remove and clean. The magnets won't rust themselves, if submerged. Great video sir!

[@r.j.sworkshop7883]

Jeez Jon, you own a dump truck, why don't you just go and get some fill material instead of scraping the ditch??? Too soon? Sorry. :) One thought about the tank, you could hang a magnet in there to try to catch some more of the junk as well. I always glue a magnet into any closed boxes that I build (oil pan, trans pan, axle case). If the material flow continues, you could use a magnet with a hole in it, in the tank and tie it to the sender somewhere so that you can pull it out to clean the magnet off. Nice work, and thanks for bringing us along.

[@johnlambt7339]

Put a neodymium magnet in your excavator fuel tank tie it to a stainless wire to catch all the rust. I’ve bought neodymium magnets with holes on eBay-they are strong and may grab all the rust when the diesel sloshing around. I enjoy your videos and have certainly benefited from many of your trials and tribulations. Lol Best regards John

[@realairplane261]

I enjoy this guy. He is always polite, uses appropriate language and has a positive approach to his work.

[@02blackLightning]

Bend the line inside the tank upwards about an inch or 2. It will help alot from picking up the stuff at the bottom. Has helped me many times in those same situations.

[@johnobiro5202]

Love your stuff Jon. Back in the 80’s I was having the same problem with my Diesel tank on a JCB, so I cut a hole out large enough to get my arm in to clear the bottom of the tank. I made a plate bigger than the hole, put a rubber gasket on and used self tappers to hold it on. It turned out a good idea at the time. I was able to access the tank later on. Keep up the great content Jon. 👍🔧🇬🇧

[@MitzvosGolem1]

I had a JCB 214 has large inspection covers so I could clean fuel and hydraulic tanks. Best to do so every few years. Cheers

[@paulmanson253]

A few observations here. Your comment about pressure washing the tank. It can be done without causing rust. Soda,Sodium Carbonate,or dishwasher detergent can be used. Just about any alkaline product will stop ferrous metal from rusting. A previous comment suggested bending the end of the tank fuel feed pipe up a little. Very good idea. One thing in particular I got bit on,years ago. I am guessing the Diesel fuel injection rack has an electrical solenoid doing the on/off cycle. Make absolutely certain the lever is going all the way on during the run cycle,and all the way off during shutoff. I there is any question about the proper operation of that solenoid,either replace it or replace the mechanism with a Bowden cable assembly where you personally push the lever to full on or full shutoff. Hesitation and uncertain running can be caused by what I just described, at the very same time as a fuel contamination problem. And with two causes,endless hate is the result. Lastly,just about any competent shop manual for a Diesel engine is going to have a flow chart for diagnosis. I hope you have such a manual. Please read that part carefully. Don't go chasing your tail unnecessarily. Been there. It is no fun at all. All the best with your beast.

[@AncientApparatus]

I admire you in so many ways it's hard to know where to start but the biggest one is how diligent you are when it come to cleaning before you get started working on anything. It drives me crazy when I watch KZbin videos of people working on cars, or anything for that matter, without power washing or degreasing them First. I'm always impressed on how thorough a job you do cleaning Anything. But your idea about using a sandblaster as vacuum was the best, Thank you!

[@Clarkejt112]

Leave some evaporust in the tank for 24 hours and then drain it. I’ve had awesome success with old motorcycle tanks that way.

[@NordicSpartan]

An observation, may or may not be of value. How about changing the orientation of the T fittings so that both filters encounter the same resistance? That way, they should clog at the same rate, in which case your explanation of the service frequency would hold (even more) true. Great video as always, especially enjoyed using the venturi effect for sucking and blowing!

[@tonypiunno1087]

I had the same thought and comment before I read yours

[@Riverbankproducts]

Tees are in backwards. That’s why the one filter is not working until the first one clogs up

[@edwardhugus2772]

My thought was get rid of the "T" connector and use a "Y" connector.

[@bwanadave76]

Ha! Just made the same comment!👍

[@brodie7528]

I am a new viewer; I have put some thought into your fuel filtering problem. Use a five gallon plastic bucket filled two thirds with diesel; set it aside. Now with eight or more inches of rubber fuel line, secure a weight (maybe a piece of lead as long as lead does not react adversely to diesel) three or more inches from one end of rubber hose. Now, at the same end of hose, secure an air tight float. Then put a filter at the same end of this hose. Now put this in your bucket of diesel making sure the hose fills with diesel. Add or delete just enough of the weight so the float will maintain the filter at a position approximately four inches from the surface of the diesel. When this adjustment is to your satisfaction, connect and clamp the opposite end of the rubber fuel line to the intake at the bottom of the fuel tank using long needle nose plyers. The sediment within your tank even with the rapid movements of your machine should not be able to reach the intake filter within your tank. Maintain high level of fuel in tank.

[@royb.1441]

The graph helped me understand the two parallel filter lasting longer than twice as long (for your situation)

[@mackenziehaines1976]

When I was a diesel mechanic we would do what we called a hot shot. We would drain it, put degreaser inside, scrub it the best we could with a rag on a metal rod, then get the heated pressure washer as hot as possible and blast the inside out then run a fan into the tank to dry it out. That was the best way to clean the crud.

[@davesvoboda2785]

Keeping the tank full will keep the walls from rusting, but if you don't purge the water frequently, it'll still rust the bottom.

[@mehdimarashi1736]

I'm not talking out of experience with gas tanks here, but at least theoretically, it shouldn't be the case. Think submerged structures, they never rust when they are fully submerged. I have seen bridge foundation piles dragged out of a river bed, as good as new after 50 years of sitting submerged.

[@davesvoboda2785]

@@mehdimarashi1736 I am speaking from experience. I once had a motorcycle on which the fuel tap didn't reach to the very bottom corner of the contoured steel tank. Most copies of that model bike had rust start in that bottom corner, within a few years, if you didn't treat it with alcohol periodically. Even gasohol can get too much water to absorb in a low tank after a long time sitting.

It might be worth installing a beacon on the roof of the excavator, or having a small magnetic one you can put up there when working roadside. It really helps people distinguish operating plant next to the road much earlier to give you more room or reduce speed a little.

[@cryptology3975]

To bolt a plate to the outside of the tank, you could fabricate a frame/flange that would sit on the inside of the tank to receive your bolts, sandwiching the tank wall. You could also secure it to the inside of the tank with external bolts, effectively using the tank wall as a bulkhead.

I like the idea of a string of magnets on a wire, it should catch all the rust and metal crud. Have the magnets sitting on the bottom and you can retrieve it periodically.

Jon interesting video@s you keep it up , I have some vintage tractors here on the farm in the UK and rust in the the fuel tank is old problem , The way I overcome this was by putting an piece of light chain on the end of fuel cap long enough for it to roll /slide around the bottom of the fuel tank , when the machine is in use it will do the cleaning for you , you may have to change some filters to begin with but after that the fuel tank will be like new inside , best wishes Ton van den Berge UK

[@Echohb]

Invert your tubes on the tee after the filters. That's a nice way to help even out your parallel flow... The filters that feeds from the branch of the tee before the filter should feed the inline part of the tee after the filtre. That way both filter has tee branch on his circuit (each circuit get a tee branch and one inline tee...). We see that kind principle in hydronic heating system to help naturally even out the flow in multiple radiators circuit. Inverting the tubes is an easy task and also I'm curious to see if both filters would fill up on start-up with this mod.

Some really ingenious comments from the viewers. I remember a movie about drug runners from the 80's where their plane had 3 fuel filters in parallel.

I remember seeing an old advertisement from the 1940s maybe? It was basically a Venturi attachment that you’d stick over your car’s exhaust pipe, and it had what was effectively a long vacuum hose coming off of it. You’d just use that to vacuum out your car’s interior, blowing all the crap out behind the car with the exhaust I guess. Definitely gave me a laugh.

Krud Kutter is great for removing rust from a tank,you can buy it at home depot. It will desolve it gentally and neutrilize with water.

One way to do it: Cut the hole, put a flange on top of it, drill bolt holes, remove flange, use flange hole pattern and drill holes to view port plate, put bolts to flange holes (note inside out) and weld bolts on the flange, put the flange inside the tank, bolts sticking out of the tank shell holes, tag weld flange to tank shell.

Concerning inline fuel filters, NAPA has 2 different inline fuel filters. One is a gas filter, the other is a diesel filter. Be sure you get the correct one. Gas will flow through a diesel filter much easier than diesel will flow through a gas filter. Using 2 filters in parallel is a very good idea.

I have already installed a cheap eBay water separator/filter but that tank is going to have to come off either way. Great video!

[@OldSneelock]

Good tip on the dual filter. Late suggestion: You can cut the wall of the tank in a rectangular opening and then cut a 1/4" thick backer plate so you can tap the holes. Have the backer and the cover overlap the tank opening an inch on a side. Then fasten the backer in with a couple small flathead screws. Drill and tap the tank, after the backer is installed, for as many bolts as needed to hold the cover plate securely. Put a good gasket and some sealer on the gasket. Bolt the whole thing together and Bob's yer uncle.😁😎

[@americ79]

I love what you did with putting the filters in parallel. I think while I had the tank apart, I maybe would’ve clean the tank out with soapy water. Then ran a hose through it, then took an old refillable fire extinguisher filled with diesel and sprayed it in the tank just to rinse the water out of the tank. I think there’s a lot of small dust like particles that are clogging those in-line filters pretty fast. Thanks for the video I always learn something new from you!

I'm disappointed you didn't plough the dirt into the drive with the excavator bucket sticking out into the road...🤣🤣 Ideas re the tank/fuel system: 1. stick the nozzle of a power washer through the sending unit hole and move it about. With the drain plug removed the pressure and water should dislodged any loose rust particles. 2. seal and fully fill tank with a mix of water and STAR BRITE Star Tron Tank Cleaner, Leave it sit for 24/48 hours, then empty, rinse and repeat. 3. use a metal, or even a plastic screen filter before the pelted paper filter to catch the big stuff. 4. attach some neodymium magnets, with tape, so you can remove them when replacing the filters, to those plastic inline filters you're using so they catch some of the rust before it gets to the filter paper. It'll should make the filters last a bit longer 5. place some strong magnets near the pickup tube in the tank to catch the rust as it floats by

Great channel, Farmboy.

Have you considered putting neodymium magnets near the inlet so the rust flakes get snagged as they approach the pipe? The rust will build up a ball in the tank right next to the magnet, but you can slide that towards one of the ports and out, by sliding the magnet along the outside of the tank. Our Kubota has a magnetic filter that runs the fuel through a small detachable chamber that sits in a ringmagnet, and I absolutely love that design. The chamber is basically just a little cylinder like those things you turned your camera film in with. Pops out for easy cleaning, and is bright orange which is EPIC because (blush of shame) I drop everything that is not attached to my body

Sounds like you've got it working well. My only thought is maybe bending up the fuel pick up pipe in the tank to get if further from the tank floor. The sediment was pretty small so might not make much of a difference.

if you turn your T for the 2 inline filter you will get equal (ish) flow to both of them bottom of the T is the inlet, left and right of the T sends fuel to the filters making the fuel make a right and left to each filter rather than 1 filter going straight and the other with a turn great content as always!! what about using a fuel bladder inside the tank.. trying to think out of the square rusty box you have plaguing your efforts

[@glenpaul3606]

Use Ospho (phosphoric acid) to neutralize the rust. It turns iron oxide into iron phosphate which is inert. You can then vacuum out the loose black particles and even rinse with some diesel and drain be removing the drain valve. A screen over the pick up tube is a good idea.

So just my two cents my friend I have a mini excavator that had the same pre filter you have and it kept dieing like that. I figured out the hard way that them time of inline filters wasn't ment for diesel I changed to the correct filter and problem went away. Keep up the good videos

[@AntonioClaudioMichael]

Good idea with the 2 pre filters makes perfect sense WITH them in parallel @FarmCraft101

I just saw your excavator fuel filter problem video! Here's another fix that I came up with after my wife started complaining about the washer water slowly filling; taking to long due to sediment plugging the metal screen with being on a well. I installed a whole house filter inline to the washer hose and it's been over a year since I've even looked or heard of any complaints. Someone also suggested magnets which is also a good idea I think you could throw a couple into the bottom of the filter or even glue them to the outside of the filter case. This would extend your run time even more due to the size of the filter. "Oh darn" now I'm going to have to take a peek at my filter. Thanks for your great videos!

I think your solution works great! Yes, there are other ideas. Everything is done before we see this.

Word of advice if you want to avoid changing those but also get the gunk out of your tank. Which is what I'm currently doing now... Buy a universal fuel filter for a fuel depot/ pump (spin on) reduce the 3/4 down to 1/8 inch then use the 1/8 by 5/16 barb. then install that before your pre filter to get the stuff out, and use that inline as a visual cue. replace the spin on as needed.
