NEW ULTRA QUIET CHINESE DIESEL HEATER FUEL PUMP / REVIEW & TEST

[@offshoretinker]

Hi Mel. I cured the problem by putting the pump in a 300ml pop bottle and pouring mould making silicone round it. When cured I removed the pop bottle and had a pump encased in about 10mm of silicone rubber. As simple and effective as it gets.

[@BigVanSmallWorld]

That's a clever solution! Encasing the pump in silicone rubber is a great way to reduce noise. Thanks for sharing your method!

[@RoaminRob]

Genius!!

[@andrewcrowe164]

Hi Mel, personally I don’t think there’s any difference between the pumps. An added plus to my noisy fuel pump is that the Mrs hates the sound of it and refuses to come with me during cold weather so a clicking sound is a small price to pay for what would otherwise be a much louder and annoying noise in the background for the entire trip😂

[@philfromsalisbury4538]

I love hearing the ticking noice, its reassuring to hear the ticking to show the CDH is working !!!!!!!!

[@NoelG-IRE]

The pump is not noisy. It’s the vibration that causes the noise. You have to suspend the pump. If you bolt it straight to an any surface it will make noise.

[@RolyHough]

I bought this a couple of months back Mel. It’s brilliant and after a couple of days it went even quieter.

[@BigVanSmallWorld]

Nice one! Glad to hear it’s working out for you. Quiet heaters are the way to go!

[@theonlywoody2shoes]

Remember, if comparing noise levels on KZbin, go into the settings and untick the new “stable volume” option. Whilst this can be useful with lessor content creators who don’t manage their volume settings (not you obviously) it’s not great if it amplifies quieter content when you are attempting to determine different volume levels. Mine is off, but I couldn’t hear much difference. Thanks for the information and educational/entertaining content.

[@nicholaspayne8151]

I’ve just fitted one of these but only because the original on failed, it’s a little quieter but not much. The only problem I’m having is get the fuel bowl to fill, I have a large amount of air in the bowl.

[@BigVanSmallWorld]

Bummer about the air in the bowl! Just keep messing with it, and it'll figure itself out. You've got this!

[@nicholaspayne8151]

@ that’s my thoughts, I like messing 😊

[@bettyourcampervan]

Great video Mel! I have mine under Betty, wrapped in pipe insulation and cant hear it 🤣

[@BigVanSmallWorld]

Sounds like Betty is living the peaceful life! She must be the quietest camper on the block now!

[@bettyourcampervan]

@BigVanSmallWorld 🤣🤣 yep!

[@steve810810]

Hi Mel. I suspended my pump under the chassis with cable ties and then wrapped the pump with an obscene amount of butyl tape I had left over from the build. Having a fixed connection to the chassis resonates Only problem was is that the mot chap wasn’t happy with a swinging item under the chassis.

[@BigVanSmallWorld]

Nice move with the cable ties and butyl tape! Just keep an eye on it and make sure it doesn’t start doing the cha-cha under there! 😂

[@Miles-pg7gf]

Think I won’t bother thanks mate 😂

[@BigVanSmallWorld]

No problem at all! Everyone has their preferences, right?

[@bevmarks9921]

When using the "dB" meter it is important to have it exactly the same angle and distance from the noise source.

[@BigVanSmallWorld]

Totally! Gotta keep it at the same spot, or it’s just gonna be a game of “guess that noise level”!

[@travellingjournalist966]

The upgrade has a higher pitch which would be more annoying but if it were under the van it wouldn’t be noticeable another great video mate

[@BigVanSmallWorld]

Thank you for the positive feedback really appreciated 🤙👍🍻

[@Charlemagne1367]

Couple of years now running the bog standard one, suspended with zip ties on the under carriage, can't hear it.

[@BigVanSmallWorld]

Zip ties: the unsung heroes of the DIY world! Who knew they could double as a fuel pump suspension system?

[@DeePaignall]

Good work as usual Mel! Sunster who innovate a lot of tech in these heaters have a new version which is really quiet - I bought one of their toolbox type heaters and the pump is silent!!

[@BigVanSmallWorld]

I really appreciate your kind words and the tip about Sunster! It’s always great to hear about new products that improve our experience. Thanks for sharing!

[@richardmills9831]

To my cloth lugs Mel, I think there is slightly less clinking sound with the new 'improved' filter. Happy new year Mel. Soon be 50 K subscribers mate.

[@BigVanSmallWorld]

I really appreciate your support and feedback! Wishing you a fantastic New Year, and let’s keep pushing towards that 50K it's all thanks to people like you so thank you my friend

[@DA11NOON]

Hi Mel happy new year 🎉 Great vlog 👍 Be safe

[@BigVanSmallWorld]

Thank you so much! Wishing you a fantastic New Year as well. Your support means a lot!

I like the sound Mel, it keeps the demons away

Haha, well, if it keeps the demons away, I say it's worth every decibel!

[@jlr3636]

Keeps the Zombies away ! 🧟‍♀️🧟🧟‍♂️

[@travelswithbilbo7526]

Hi Mel, I fitted the same pump last year to our motorhome but fitted a waterproof box to the chassis and put the pump in this surrounded by foam so there is no physical contact between van and pump, also I lagged the exhaust pipe.

[@BigVanSmallWorld]

Thanks for sharing your experience! It's always helpful to hear how others are customizing their setups. Your tips could be a game-changer for many!

[@joshuacrossley4990]

I would of got one but not now . Cheers for the side by side

[@BigVanSmallWorld]

You’re absolutely welcome 🍻👍

[@stevewalker1224]

I have my pump in the engine bay of my camper, between 2 cable ties & cant hear it in the living area of the van

[@BigVanSmallWorld]

That's awesome! It sounds like you've found the perfect spot for your pump. Keeping the noise down in the living area is always a win!

[@MACK13]

Thanks for showing this to us Mel. Useful as a spare especially with the filter. Mine is still hanging happily and quietly under the camper on 4 cable ties👍🏻✊🏻👍🏻 Happy 2025 to you all🎉❤️👍🏻✊🏻

[@BigVanSmallWorld]

Glad it was helpful! Happy new year 🥳

[@simplestuff3895]

All these pumps are ‘dose’ pumps. They work by a piston moved via electro magnet triggered by the current that pushes a pre-measured amount of fuel out of the piston chamber, along the fuel line. The piston hitting the end of the chamber creates the sound, so none of these will ever be quiet. Covers are no use. I’ve seen someone use a microcontroller to change the voltage delivery to the pump, via pulse width modulation. Not sure how successful it was. The alternative is a pressurised fuel line and injector with a return feed to the tank. They don’t exist for diesel heaters. What seems to help however is increasing the resistance of the fuel after the pump. This dampens the piston hitting the end of the chamber. Many instructions do state that the pump should sit at the lowest point of the fuel line and the heater should be elevated in relation. The higher the pump has to move the fuel, the quieter it gets. But never silent. This also mitigates the risk of heat transferring to the exit nozzle of the pump and melting the end of the fuel line, if using the small diameter type. (This is a common cause of an E8 error) There’s no silver bullet for these and putting up with it is about the best strategy. We can’t have everything we want in life 😊

[@BigVanSmallWorld]

Thanks for sharing your insights! It's fascinating how the mechanics of these pumps work. Your tips on positioning and resistance are really helpful for anyone looking to minimize noise.

[@andycole2672]

I bought one couple weeks back can’t here anything from pump

[@BigVanSmallWorld]

Thanks for sharing your experience! It's great to know that the pump is living up to its 'ultra-quiet' reputation.

[@Urbanex2u]

sounds the same at 0.01 difference need more sound deading around the pump that would work coool good vid thanks

[@BigVanSmallWorld]

Yeah dose sound the same 🫶👍

[@AJ-qn6gd]

Just buy an Eberspacher pump ours in our T5 is silent I’ve never heard it either inside or outside the van in two years ! I don’t suppose it’s £15 though !

[@BigVanSmallWorld]

Silent pumps are like unicorns-rare and magical! But hey, if it's not 15 quid, maybe it comes with a free magic wand?

[@AJ-qn6gd]

@ I’ve had people park up next to me with their Chinese diesel heater running and I can hear their pump in my van !

[@jansweeney1333]

Hi Mel , I m seeing quite a lot of folks have the diesel heaters under their vans; is that something you would consider doing?? Grt video Mel, is your new YT channel up & running yet for the metal detector?? 🏴󠁧󠁢󠁳󠁣󠁴󠁿Jan

[@Normz-y1969]

Nice try Mel sadly the difference wont send sales figures sky high 🤔i read on a FB feed a guy wrapped some dense foam around his heater pump, suspended it with ties and claims its done the trick... worth a try i guess. Happy New Year mate and keep those vids coming 👍

[@Baloovanz]

Hi Mel, do you know if this would fit tge D2 Erbaspaecher?

[@BigVanSmallWorld]

Hi there! The D2 Erberspächer is a great unit, but I recommend checking the specifications of both the heater and the fuel pump to ensure compatibility.

[@Baloovanz]

@ ok great. I was thinking more about the connector compatibility but you make a good point. Cheers bud

[@tamwestwater]

Looks exactly the same as the one I’ve had for a while- not ultra quiet but I no longer notice it

[@RaymondSharrocks-lw6mt]

Then old pump much quite than the new pump...no bother mell ...Happy New year to you and ur family for 2025 .all the best

Happy new year 🥳 🍻🤙🫶

[@peterburgess4637]

Have two on our Sprinter, one for the air heater and one for Webasto thermotop water heater I mounted both pumps on rubber bobins off ebay, so isolating them from the chassis, nice and quiet now.

[@BigVanSmallWorld]

Thank you for sharing your experience! It’s great to hear that the rubber bobbins made such a positive impact on the noise levels.

[@gaz1226-j2x]

The ticking is definitely louder mate, I certainly won’t be bothering.😏

[@stuartalexander1595]

The noise from my diesel heater doesn't bother me. It's only being cold that bothers me.

[@BigVanSmallWorld]

Totally get you! As long as the heater's doing its thing, who cares about a little noise, right?

[@oldtimerlee8820]

I couldn't tell any difference. What happens when the fuel filter needs cleaning or replacement? Happy New Year to you and Becky.

[@BigVanSmallWorld]

Thanks for watching! If you didn't notice a difference, it might be worth checking your fuel filter-keeping it clean can definitely impact performance. Happy New Year to you too!

[@oldtimerlee8820]

@@BigVanSmallWorld Can you clean or replace the filter in the pump? Wouldn't an in-line replaceable filter be better in the long run?

[@cottonfoo]

As someone with no experience of any of this, I wonder if any are quiet? Does spending more help? I'm not sure it will given the nature of them. I think all you can do is use sound insulation or something.

[@BigVanSmallWorld]

Thank you for your comment! It's totally understandable to be curious about noise levels, especially with diesel heaters. I appreciate your input and hope my review helps you make an informed decision!

[@Deiseboi]

Never hear mine as its on drivers step along with filter as tapped into fuel tank which is under passengers seat...plus left bulkhead in which has few layers of loft insulation and 25mm insulation board then 7mm tongue and grove..due to my toilet/shower area is located by bulkhead have installed a bifold shower door ...so sleep perfectly 😂.....plus your right there no difference other then the filter.

[@BigVanSmallWorld]

It sounds like you've set up a really effective and quiet system! Insulation definitely plays a huge role in keeping things peaceful. Thanks for sharing your experience!

[@Ritarelay]

Thanks Mel… was looking at a service on ours and wanted to know if this was any good.. I shall be buying a couple so we have a spare on board! As we will be full time in the not so distant future :) so building a “must carry” kit.

Awesome, glad I could help! Having a spare is always a good idea. Let the adventures begin! 🚐💨

Ticking don't bother me as long as it keeps me warm.😊

[@DJingDad]

As an ex-HGV driver like yourself Mel, I always hated putting the heater on at night because of the noise. I dont think any of them are quiet. Cant you wrap it in that black foam flooring stuff u got or better still, install it on the outside of the van lol

[@BigVanSmallWorld]

I totally understand where you're coming from! Noise can be a real issue with heaters. It's definitely worth exploring some soundproofing options or even relocating the pump if possible.

[@rhiantaylor3446]

Based on the comparison, I would buy the new pump.

[@BigVanSmallWorld]

Glad I could help 🫶👍

[@trevorhartley5166]

Meet the new pump same as the old pump

[@BigVanSmallWorld]

Ah, the classic case of "if it ain't broke, why fix it?"

[@gary.mardle]

I’m surprised these are classed as new. That is the same pump that came with my cheap Chinese diesel heater back in 2024. It works a treat and has the benefit of the filter (I still have an inline filter as well, which came with the kit).

[@Desmond.TuTu.]

Back in 2024 … that was eons ago, surprised you can remember that far back 😂

Red diesel!??? My diesel is yellow 😮 Is the red diesel cheaper and what is it called!? Regards Rickard in 🇸🇪 Sweden

[@BigVanSmallWorld]

Great question, Rickard! Red diesel is typically used for off-road vehicles and is often cheaper due to lower taxes. It's officially known as "gas oil" in some places. Hope that helps!
