Electric Fuel Pump Conversion On a Lawn Mower.. Does it work?

[@jebjr100]

Wired mine to accessorie wire off key switch, good video

[@JLPicard440]

Excellent! Yes that's another option! Thanks for the info.. 😀

[@onesecureone]

Good job I like your double heat shrink idea and to help clarify the reason it doesn't matter what wire goes to either post on your on off switch is the only difference is what direction on and off is on the switch

[@JLPicard440]

Excellent! Yea I've done that double heat shrink thing since forever... 😂. Especially on a critical connection....

[@sjjvddyumiherhv3709]

But how theu don't over fill the carburetor on idling? They are on all the time without the ecu can someone explain before i do the conversation

[@jon796797]

Great, informative video that will save a lot of people a lot of trouble who have Kohler engines. Those of you cool to your carburetor forget that vacuum fuel pump and put the electric on save yourself a lot of trouble down the road

[@JLPicard440]

Great thanks for the great feedback and information!... 😀

[@patrickhawkins2970]

Thanks!

[@JLPicard440]

Thank you so much for the super thanks!...

[@olfatskootch]

Great video! But you can wire that pump right through the ignition switch on the mower

[@JLPicard440]

Yes you can do it either way... 😀.

[@Coach.Lewi.1979]

How would you do that?

[@JLPicard440]

@@Coach.Lewi.1979 I forget which wire is 12 volts switched with the key. I believe the wiring diagram is available on this time cutter free to download. With that it's pretty easy to determine which wire it is that you can hook to. Or you could take a volt meter and test each wire to see which one will work.

[@jimibmore]

@@Coach.Lewi.1979 Most mowers have a fuel solenoid on the bottom of the carburetor that energizes when you turn the key on. That's the easiest place to get continuous 12 volts with key on.

[@JLPicard440]

That's great! I hope it holds together for a good while this time.. 😀

[@CorbinAce]

Nice job Rudy. I figured you were going to make a video. I did one little thing different. I connected the Pump hot wire to The Fuel Solenoid wire so the pump shuts off when I shut off the ignition. I can guarantee I would miss shutting off the pump. (like my shop air compressor.) :O) I also put a toggle switch just so I could shut off the pump if for some reason I needed to, and of course the inline fuse. Them pumps only draw about 4or5 amps. I am curious how long the elec. pump will last. I replaced the vacuum pump every year. Even the OEM. I rather buy an electric pump every year. they are half the price of the vacuum pump. I do like the elec. much better. John

[@JLPicard440]

HI John! I wanted to give you a shout out in the video, but I couldn't remember which video we initially were collaborating on..🙂. I thought about connecting it with the switch, but wasn't sure of the amp draw and didn't want to damage the ignition switch or go through any under-rated wires. We've (my bother and I) had a few old hot rods with electric pumps and always had a switch under the dash, so I did it this way to remind me of that!.. 😂. Thanks again for the idea... I don't know how long the motor will last, I probably only use the mower about 8 hours a year so we'll see.. Sitting might be worse for it than running it.

[@CorbinAce]

@@JLPicard440 I don't need a shoutout. I have no way to make a video anyway. Like your' video it's the best one in here. Well done. Right now I am not getting any power anywhere no click.. I am on my way to trouble shoot the wiring. I dismantled the mower to slap a quick paint job on it while replacing the belts and pulleys. (can't do anything the easy way) I must have messed up a wire or safety switch. The Paints done, belts are on and ready to go. I miss my younger brother. Many, many miles riding motorcycles together about 50 years riding..

[@JLPicard440]

@@CorbinAce Oh no! It's always a great feeling when you put something back together and it doesn't work.. Yes I would guess a safety switch. Hopefully you've gotten it back on the road by now since you're response was yesterday.. Sorry to hear about your brother.. ☹️

[@CorbinAce]

@@JLPicard440 Thanks Rudy my brother was my best friend. He was 69 when he passed 8 years ago.. I am 86 as we speak. I hate it when things don't work. I think I found the culprit though. I removed the battery and checked out the mess of wires and found the wire to the Amp meter was pulled out of the wire connector. I'm heading out there now to reassemble and check it out. I'll let you know. I should get a new wired connector and ignition switch today. I keep this up I will have a new mower. LMAO. For twice the cost! :O)

[@CorbinAce]

My neighbor sent me a high fi as I was mowing my lawn. It was the amp meter wire that disconnected that killed every thing. It is still not running good enough for me. I had to cut the grass. I have a Carb. rebuild kit I bought when ordering the belts and pulleys so I will rebuild the spare intake that I have and pull a swap. Been good talking to you. Will drop a comment now and then. John

[@wandaboiano9458]

Very nIce video and thanks for providing links to the parts. Pump turned on initially but only worked for about a half hour then quit while cutting grass. Can't get it to run. Ruled out ON/Off switch by by-passing switch...still no power to pump. All wires are intact. Battery is good. Any suggestions?

[@JLPicard440]

Arrrgh. Did you put an inline fuse with the pump? If so, that could be the culprit. If the fuse is good, I would connect power directly to the pump and see if it runs. If not, maybe it went bad. Mine is actually still working and I just used it the other day. No leaks or problems.

[@dcarter5087]

Nicely done

[@JLPicard440]

TYSM! I really appreciate that.. 😊

[@dtblessed]

Hello thank you for the video, i was hoping you would give an update on your new electric fuel pump. how is it holding up? is the carbuerator flooding on you? thanks in advance .

[@JLPicard440]

HI, I've only put a couple hours on it since the fuel pump add, but so far so good and no problems at all..

[@d.l.harrington4080]

I think this will help me with my old Ez-Go Golf Cart vac fuel pump. But why not wire it to the ignition circuit? Ignition on, fuel pump on. That way you don't forget to turn it off. I think there might be a safety issue wired directly to the battery.

[@JLPicard440]

It's possible, but I like to shut off the fuel pump and then let the engine run for a while to drain some fuel out of the carb. Just a quirk that I have. I think one will hear the fuel pump running if they do forget. But there's no reason that you can't hook it to the ignition switch. Just make sure and get a very low pressure pump.

[@d.l.harrington4080]

@@JLPicard440 I am thinking of adding a pressure relief and fuel return line like they do with cars. That would ease my mind.

[@JLPicard440]

@@d.l.harrington4080 Yes that's a good idea.. 😀

[@rdoulahen]

You didn't add a regulator to control fuel flow. Issues?

[@JLPicard440]

HI, I haven't had any issues at all. I used a low volume pump.

[@rickeycrutchley47]

What happens if there is a vacuum problem causing the original fuel pump from working?

[@JLPicard440]

The engine should create vacuum if it's running. I've seen the rubber boot that comes off the valve cover dry rot and therefore it's full of vacuum leaks. Did you check your boot?

[@ORTEZW]

Best power source for your fuel pump. Is the line that gives power to the carburetor solenoid if you have one most tractors have a solenoid on the carburetor these days. 12 volts and it operates when the key is on and the tractor running and when switches off power is automatically off to fuel pump. Just a share

[@JLPicard440]

HI, Yes I agree! You can certainly do it that way. I wasn't sure if the ignition switch could handle the extra load of the fuel pump so I was being cautious... But my guess is it would have been just fine...

[@michaellowe3665]

I might do the same thing, but use a relay just to be sure.

[@jeanlawson9133]

Awesome thanks 👍

[@JLPicard440]

You're welcome!

[@jimkurk5575]

just got done doing about the same thing on my simplicity vanguard 16hp, took the anti backfire thing out years ago and had a gas shutoff on, the pump is wired to the headlight so all i do is shut off the headlight 3-4 minutes before i quit and idle it down and it runs out of gas and stops with no backfire issue

[@JLPicard440]

Great idea! Thanks for the feedback... 😀

[@mohmedhosny6094]

Good done My question Electric pump can put over fuel chocked engine

[@JLPicard440]

If you mean a flooded engine then you should turn off the pump and try to clear the fuel out ..

[@michaellowe3665]

I considered this, but was afraid the electric pump would make too much pressure and require changes in the carburetor. Is that an issue?

[@JLPicard440]

HI, You have to get a low pressure pump. The one I used is a 2-3.5 PSI pump. The one I used in the video looks like is no longer available, so i've updated the description for one that is still available...

[@michaellowe3665]

@antagonizerr cars use a return line because it's a better way to maintain pressure accurately. The regulator keeps the rail pressure constant while the pump can flow constantly. Without a return line on a car, all the fuel in the entire supply line would have to nearly stop when you let off the throttle, then suddenly flow at full capacity if you step on the throttle. The pump can't suddenly move all that fuel instantly. With a return line, the pump flows the same amount of fuel at a constant rate, and the only thing that changes when you step on the gas is that less fuel goes back to the tank. I looked into these little pumps since then and actually installed one. They are self-regulating because they have a diaphragm that limits how much pressure they make. They are low pressure. The fuel bowl on the carburetor actually regulates what goes in the engine, and the fuel line is short, so you don't have over-pressure and starvation problems. The one I installed works great. No return is needed.

[@timd5597]

Did you need to mount pump lower then fuel tank?

[@JLPicard440]

I don't think so, but I think it'll automatically wind up lower if you mount the pump to the frame

[@alfonsochester4701]

Great video

[@JLPicard440]

Thanks!

[@JohnBLogan]

What brand & model is the pump?

[@JLPicard440]

HI, it was one I got off Amazon.. The main thing is to get one that's low pressure... I think this one is 2-3 PSI..

[@ToddCranston]

Hook power in with the key. When you turn the key on, power come on to the fuel pump.

[@JLPicard440]

That's another way to do it. I prefer it on a switch myself... Thanks for the feedback.. 😀

[@Flatfoot2282]

Excellent video and it answered all my questions. I have an old Miller Trailblazer that is having fuel issues and putting an electric fuel pump was my plan. I can't get to the gas tank without having to pull the motor so I'm thinking an external gas tank may work with the electric fuel pump. Thanks for posting this.

[@JLPicard440]

HI, yes it should work. I usually recommend to get the low volume pump... 😊

[@jimkurk5575]

want to do an external also, thinking about using an outboard motorboat tank and just taking it to the gas station and fill it and then back on mower. gas cans are messy

[@JLPicard440]

Yes that's a good option. Hopefully it'll hold enough fuel for a few yard cuts. Seems like it would be a lot more headache to load the mower up and take it to the gas station all the time... 😎

[@frankdove4869]

What's wrong wiring it to the key when you turn the key on the pump comes on and turn the key off it goes soft some people forget to turn the pump off

[@JLPicard440]

HI, there's nothing wrong with that. Although I have discovered when I park the mower I like to shut off the pump and let it run for about 30 seconds to drain some of the fuel out of the carburetor. Not really necessary unless parking for the winter, then it makes it easy to shut off the pump and let the engine run until it quits... Can't do that if it's wired to the key switch.. It's just quirks that I have... either way is fine.

[@kebo57]

Ummmm, why have two fuel filters? If that mower is ever sold, the new owner might not realize it has two, and thus only change the obvious filter while neglecting the not so obvious filter, allowing it to become clogged up over time. Also, with way you wired it up, it will run the battery down if you accidentally leave the pump on, right? Otherwise, good job with the conversion to an electric fuel pump.

[@JLPicard440]

HI, yes I could have put the pump on the key switch so it turns off with that. For me personally I like to shut off the switch and let the motor run for a little while so the carb doesn't stay full. For winterizing it's nice to just let the motor run until it quits to get the fuel out of the carb. IF it's hooked to the key switch you can't do that. But either way is fine. Yes it will run the battery down! It is loud enough where it would be hard to miss even if you forget you'll hear it running... I don't remember installing 2 filters? I'd have to look at it and see what I did. You're right, 1 would be better.

[@justsayin7937]

Not really a need for a switch. You can wire into the key switch using the same terminals that actuate your fuel cut off solenoid.

[@JLPicard440]

Yes true.. I like the switch, even though I could have done it another way.

I like the switch option better, rather than splicing into the factory harness.
