different higher frequency base is carrying stronger the old one

[@KeithOlson]

Thanks for sharing! The first thing that came to my mind to make the pump be *MUCH* quieter is to firmly attach a container filled with loose lead shot to the pump itself, then isolate the pump + weight from the structure of the van with foam cushion/very flexible fuel line/etc. That will *DRASTICALLY* reduce vibrations being amplified. Another route is to pick up one of these actual silent pumps that a fellow in the UK makes: kzbin.info/www/bejne/foC5h6KBg5qmo9U (Email to contact the maker in the description.) Cheers!

[@bryansilcox9590]

New pump just a bit quieter , not a lot in it thou

[@martinballs9785]

not worth 30 quid

[@hfcwudya2965]

You got ripped off mate!!!!!

[@shed.projects5150]

I have found that the best thing for making the pump SILENT, is to wait until your in your seventy's, and your hearing goes . Works for me. Job done.

[@greghohensee4067]

What?

[@sparkiekosten5902]

You'll have to speak up I am not wearing any pants!

[@romakayak]

My pump is clad with playdoh, placed insight a 1 litre Ice cream box and mounted vertical. Very quiet, very quiet.

[@BigVanSmallWorld]

Well that’s a new one on me well done 👍🤓👍👏👏

[@PCongeries]

I will try your idea too. Thanks mate

[@hunter00047]

I know it's not recommended, but my solution has worked for the last 3 years and I can barely hear the pump. It is just to replace that stiff fuel line with model aircraft silicone rubber tubing all the way up to the short back hose that comes with the pump. The pump is suspended with silicon fuel line rubber as well. Once my enclosure is replaced it's peace no ticking. My fuel run is 2 meters. Keep up the good work.👍👍

[@BigVanSmallWorld]

That’s brilliant 👍

[@debbie62140]

Hi Mel, it is a tad quieter, but I wouldn't say 'ultra' quiet and certainly not £30 quieter. Although the ticking didn't bother me too much in my T4, I experimented with sound insulation. The best method I found is to build a box out of 20mm softwood big enough for the pump to fit in and pack it loosely with that cheap foam flooring underlay. Then I hung the box with rubber cords scavenged from an old bungee. By the way, your lighting is much better.

[@BigVanSmallWorld]

Thank you Debbie 👍

[@ericbrockhus2518]

That was exactly what I was gonna comment here. Well done.

[@Bovine-em8uy]

I find the fan is far louder than the ticking pump

[@KungFuPanda50077]

Fuel line is going down under the van so you can install your pump under the car. Just put an insulation tape on top of it and that's it.

[@tonyfrancis9793]

Hi Mel, nice video👍. I suspended my standard pump under the van from a short piece of thick rubber (a peice of a floor squeegee) about 4" long and, once it reached temperature, you just can't hear it at all inside the van, not even in the dead of night! Even when its getting up to temperature the clicking is only faint. I can send pics if interested?

[@thomasmarkie7172]

Can the heater work without a pump if gravity fed.

[@johannesgross1732]

The ticking sound is being transmitted via longitudinal waves along those hard plastic Diesel tubes/hoses. If you want to avoid this you need to build a loop at input and output and hang the pump loosley together with those loops so it can swing freely.

[@bhg00]

Thats it

[@jeffreyhill3960]

No change to me.

[@steveg2509]

pro BS

[@cerealtiller]

I use a 100 cm. length of rubber Diesel hose (3.5 mm I.D) either side of the Pump..with a loop in it.. the Pump is then very Quiet.

[@lessmith8540]

Hi Mel, next time you remove the pump, use brake line clamps to squeeze the rubber tubing, then no air in the system or spillage, or having to 're prime the pump. Great vids keep it up.

[@kurtwagner16]

Or just stick the old on in there for a moment and only switch for the quick change.

[@bobvilla4003]

The new pump is definitely quieter. Even if folks don't think the difference is worth the 30 pounds, you now have a spare pump. I would think the pump would be one of the more common items to fail / wear out and with a spare already in hand, it is now a no worries situation. Thanks for Sharing and Cheers from San Diego.

[@BigVanSmallWorld]

Thank you buddy I’m happy to report that the pump is working great and as actually improved now that I have used it for the winter 👍😊👍

[@HILUXCHAINSAW]

Wrap bubble wrap around the pump, put the wrapped pump in a box and fill the box with expanding foam. Then fix the box to the wall with screws going through rubber grommets. If the pump ever needs changing you can just pull of the foam off and the pump will still be clean inside the bubble wrap.

[@patriotjoe3110]

The foam cases sold online also help reduce the sound. Using a rubber band to suspend it will also help reduce the sound transmission more than the zip ties.

[@ragnaroksangel]

Rubber bands become brittle super quickly. Last thing I want is something hanging from a friggin rubber band under my van

[@vanlifenomadfirekeeper]

I'm thinking about making a insulated box to cover the pump to make it quite. I just installed mine today. I've seen others put the pump under there van.

[@GSCt1000]

Another person on the tubes.. pulled he's heater apart and changed the bearing on the heater fan. That reduces the noise of the fan. He has his heater installed in a garage

[@castorpollux3752]

Great content! I learned some things I’m going to use. Tip: no one wants to see you moving boxes for a solid minute. Edit it out.

[@BigVanSmallWorld]

Thanks for the tip!

[@mickeencrua]

The best sound deadener is the blue towel you used to catch the diesel drips. Towelling material is by far the best for overall sound insulation. Has a sound absorption rate that is higher than most professional studio sound barriers.

[@macatac14-kt4xp]

I just purchased one of the all in one box type diesel heaters not had it running yet , but ordered a fuel pipe kit and the quiet pump which has double filtration built into it , another mod you can do to quieten the pump is a universal heater fuel pump damper .

[@regwatson2017]

If I had a little "grizzly" wood heater like that I doubt I'd ever use the diesel heater :-) You are right - the "tick" is much more subtle and peaceful. In fact could soothe me to sleep.

[@jonathandickson5055]

Definitely quieter. For those interested in quieting the motor by boxing it in remember density is what deadens sound. A metal or plasterboard box will deaden the sound far more than any kind if foam or fibre. Pvc is surprisingly good too, and of course suspend rather than fix to any solid surface.

[@aaronblueandme8127]

Mine sits under the van in a modified external electrical connection box surrounded by the silver bubble insulation. It makes zero noise and it's a really cheap modification.

[@BigVanSmallWorld]

Brilliant idea 👍

[@aaronblueandme8127]

@@BigVanSmallWorld mine has been like it for over 4 years now with no problems. It's worth a try even for your inside installation.

[@techtinkerin]

I saw a video where someone used a silent pump that squished a tube like a dialysis machine and it was 100 percent silent. I'd put it outside in a rubber box! 👍😎

[@ExpediteTravels]

It sounds a little bit quieter but if you can sleep with it on with the old pump and want to save $30 go for it Personally my all-in-one 8 kW Chinese diesel heater the pump actually puts me to sleep kind of reminds me of a clock ticking after a while I don't even hear it which is kind of Funny It's usually the time I have the most problem sleeping is my 1st night back in the Van after I'd been on some hometime trying to get reused to the sounds again

[@michaelweller6097]

I used some of the foam out of the diesel heater box to wrap round the pump and cable tied it that seems to have worked pretty well

[@andrewchalmers7422]

My diesel tank filter and pump are out side of the vehicle and the heater is enclosed in it's Own space under a seat . My noise is only fan noise.. CHEERS 🍻

[@tommotomlinson3370]

Hi Mel...by their design it's a metal piston twacking against a metal face to get the dose, you'll always get a tick until they change the design and maybe put a rubber(or something) face inside the pump, I have mine mounted underneath my van, suspended on thin rubber bungees, so much quieter inside 👍 Great vid to start discussions 🤙

[@loubakker5049]

Commented your idea. Heater also out side ?

[@Chris-yy7qc]

Absolutely worth the 30 bucks! The new pump is way quieter. Best regards from a camper van dude from germany!

[@BigVanSmallWorld]

Thank you 👍🤓👍

[@rogertaylor2924]

Hi Mel the pump noise also resonates along the hard nylon fuel pipe... So anything the pipe touches also amplifies the noise! This is best damped by sleeving both pump and pipe in soft foam pipe insulation such as armour flex and not P clipping it to the van structure! Try it!

[@BigVanSmallWorld]

Thank you buddy

[@truckerallister9080]

The most silent way to do so, is to put the diesel pump outside of the van a little above the fuel tank still is the best option, all trucks have them outside the truck.

[@claytonvicarious]

What about gelling in cold temps?

[@MLSPlatforms]

Pack it with Roxul insulation , or do what I did, pack insulation all around it then I bought a small job box , insulated the walls Floor and lid , then added 16 gauge steel over the insulation. I cut holes for exhaust tube and for air intake and outlet , I keep it outside tent and you don’t know it’s even on , the job box keeps Rain and snow out

[@markward38]

Hi Mel, thx for the science experiment mate. It gave me food for thought. I did hear someone say recently how they wrapped the pump in heat sponge and lead sheeting and it also reduced significant noise too

[@PaulGloverHowDo]

Certainly a little quieter, only a suggestion Mel but try wrapping the pump in a pair of the gaiters, them that hikers use on the bottom of there legs to stop stones ect getting in there boots. I came up with that thought whilst watching your vid, going to try it myself now, 👍

[@franklealand1181]

Definitely worth it .Anything that helps you get a decent night's sleep is worth paying a bit for . Keep up the good work

[@BigVanSmallWorld]

[@BigVanSmallWorld]

Thank you 🙏

[@ianemery7785]

Mel, please consider replacing those worm drive Jubilee type clips on your heater fuel hoses for proper fuel line clips as they give a much better and more reliable seal.

[@1elizabeth16]

Hi mel, thanks for the test, put my pump under the van, also bought a rubber pump housing off fleabay which also knocks a couple of db's off the ticking. Cant hear mine at all. Keep up the good work mate

[@andysmith5050]

Hi Mel I've purchased a fuel pump from a guy who makes his own diaphragm pumps, absolutely 100% silent....£120 but a cracking bit of kit, real game changer... Maybe you're already on the case....

[@aengus.l]

Hi pal have you got any info on where to buy one please?

[@ragnaroksangel]

Why would anybody spend more money on a pump than they spent on the entire heater? 120 for a pump is literal clownshit

[@rafo6577]

You can get these pumps for half that price. There are covers available for these pumps too, that help deaden the sound and also protect the pump if mounting on the underside of the vehicle.

[@sm7091bs]

I did it very simple to ours. Use a car radiator hose. I am into the automotive sector. So i could get one what perfectly fits around the pump. Only the connector part could not fit. Put at the other site whats is free another thick rubber hose into the bigger one so that a lot of the pump is covered with rubber. Big difference according old situation. You can hear it ofcourse but a huge difference than before and at a very comfy level. Think simpel…..

[@Retiredkiwi]

In a similar vain, 2 of mine are in short pieces of lead waste pipe, with a heavy white fiberglass(i think) insulation stuffed in the ends, and suspended from rubber hangers, which dropped the noise level a fair bit. Another system has a pump that was claimed to be quieter, bought from heatport(new zealand) called a type E (22mls/SKU: HP-10788 Brand: HEATPORT), which makes a similar difference to the one shown here, so thinking i will try a lead case on it next as well. Also going to try a lead pipe muffler, as using a 1m length on my old Chinese 5kw diesel generator, shut it up considerably.

[@alangarner4095]

Yes the new one is a little better. But the good thing is you now have a spare one if you have any trouble and no waiting for it . 👍🏻😎👍🏻

[@joshuamccabe7729]

The pumps don’t run hot at all so just in case it in foam in a plastic case job done.

[@diesel-heater-Free-Heat]

I had the same issue of tick tick driving me mad. So bought the plastic cover that covers the pump. Then with old feather pillow. Not sponge! Then wrapped the pump with 4 12 inch bungee straps. It’s totally silent and safe as the pumps don’t run hot. Then use your cable tie like I do to suspend it. Your be amazed. You see films were pillows are used to silence gun fire. Same principle. 😀

Hi Mel. definitely the new one is quieter. Anything that helps with the nights sleep is worth the investment.

Fortunately I can't relate. I have managed to tune the pump thumping out. But I will certainly tell you it shoots my girlfriend through the roof. When it is cold she manages to get over it and others have made a point of letting me know the noise is present. So there is absolutely a market for a quiet pump. Perhaps ignoring annoying noises is my SuperPower. I'm sure my girlfriend has an opinion on that.

[@texdog2772]

Mel I would mount your pump vertically. They make air and mounted the way you have it lets air build up in corner of pump = noise. They say mount like you have yours, but you cannot mount vertically on vehicle frame if you wanted to that's why they say mount at angle. I have my pump mounted vertically from four springs in a channel made of wood. it just sits there jiggling around and very quiet. Air cannot get trapped and increase noise. Plus, its completely lubricated at all times no dry areas for piston to wear out. You have room to mount vertically. Cheers Ed

[@davigbrookes3193]

Diesel ignites and burns by being compressed so the 'pump' is really a piston, which will make a noise. Try moving outside under the van.

[@Ellie_Melloy]

I don't notice much difference in your volume, the new one sounds higher pitch and the old one has more thud. I think since you've mounted yours inside the van, you'll make it much quieter by wrapping the pump in a towel or microfibre cloth and suspending it from bungee cords. I have exactly the same brand heater as you. It sounded the same when it started up and I got inconsistent performance because it's under my van and I couldn't avoid having some sections of pipe travelling downward from the pump like yours. It was the air bubbles caused by the diameter of that pipe, and changed it for 2mm ID nylon tube which gets no air bubbles even when fuel is travelling downward. I think the smaller internal diameter makes the fuel delivery more precise.

[@markbradley9725]

The new pump is quieter. There is not as much of a thudding sound. In wills(wills ware abouts) heater it sounds so quiet.. It must be a different pump.. Great video as always

[@BigVanSmallWorld]

Thank you 🙏

[@camperconquest1994]

Have you considered putting the pump underneath the van that should eradicate the noise

[@driveandsurvive]

Nice work and good to see you got a result. If possible, I recommend placing the fuel metering pump outside the van - on the underside close to the fuel tank. And as Johannes said, it's also about hard surfaces transferring the noise of the magnetically charged piston action. That equates to the rubber mount you have in place for the pump and additionally, soft mounting the hard fuel line leading from the pump to the heater injector. This hard fuel line cannot be substituted for a soft line on the discharge side of the pump, as its hardness maintains the pump pressure - so your stuck with that. On the safety side of things, I'd also recommend not placing the heater in a location that obscures direct access to, or sight of the unit (often caused by attempts to isolate the noise of the fuel pump by enclosing the unit) and have a serviceable fire extinguisher within the van at all times. Thanks for the good work and keep them coming.

[@tradmanmike3360]

All good ideas! Could you wrap the pump in the same rubber/foil baking the pump lies against to make it even quieter?

[@duncanpark1634]

Hi I’ve not looked at all the comments. I’ve used this pump for a year now, yes it is quieter than the normal ones, however you can make them even quieter by putting a rubber elbow joining pipe on both ends of the pump instead of the straight. This is advice from Eberspacher

[@Rottweilerdsq]

New pump is definitely sounds quieter and now you have a spare pump.

[@BigVanSmallWorld]

[@ArtyVanHoming]

another idea worth considering or not ,GET A SEALABLE FOOD BAG ,"YOU WILL NEED SOME DECENT TAPE AS WELL " POOR IN SOME PVA GLUE ,BECAUSE WHEN IT DRYS ITS A BIT LIKE RUBBER, SEAL THE ENDS AND WRAP AROUND THE PUMP , in the bag it may stay in a more liquid form ,so may act as bit of a sound deadening barrier , the idea maybe crap ,but its just a thought

Thank you buddy that’s great idea not sure if it will work but a good idea all the same 🤓👍

I bought a true silent pump from a guy in the UK who designed and makes them himself , not cheap but well worth the money if you want silence !

[@Dirt-Diggler]

I've seen them and they do look good but TBH I'd just fit the pump outside where they were designed to be fitted and save the money 🤔 If you HAVE to fit one inside like on a boat i use an insulated box to house the pump but those silent pumps are great if your stuck with mounting inside and can't insulate 👍

[@aaronhamburg4428]

It seems that the sound level from both is pretty much the same, just that the new one makes a more high pitched sound than the regular pump. The higher pitch may also result in less vibrations being transmitted through the wall, pipes etc. I think the best is to install those pumps on the outside and in such case getting the "ultra quiet" won't be worth it.
