All the manuals I have seen on installation say that the pump should not be placed horizontally, because it is the fuel that lubes it and one side (top side) always being dry can wear it out unevenly. Was that an issue for you? Thanks for the video.

I fit mine in a pringles tin surrounded by rock wool, works awesome, I was going to make a more engineered version but I'm lazy.

When someone finds that box in 100 years, they're gonna wonder what you loved so much about that pump :)

I am so blessed with the superpower of ignoring this noise and I didn't realize it until I watched the 10th video on this subject. The amount of effort to divorce yourself from it is astonishing. I know it is a real thing because my girlfriend makes an annoying noise I can't escape when she is exposed to the annoying pump noise. Best one I have seen is pump placed in Styrofoam cup and then the cup filled with GreatStuff. The foam sealer that comes in a can. It is surprisingly simple and it works. For me I continue to ignore both annoying noises this heater is responsible for and the second noise caused by the heater is usually silenced once she realizes it is better to be warm than cold. Usually..... Sometimes I find camping by yourself is quite underrated.

The pump is supposed to be hung between 30°-90° angle otherwise you may get air bubbles. Anyway, if it works, it works. 👍

FYI. If one wishes to learn the theory, operations, proper installation, maintenance, diagnosis and repair of this ICE I strongly suggest John McK 47. I like your suspension system! I'll employ it although slightly different configuration! Well done!

I must be the only person who actually likes the pump noise! I actually find it relaxing like a metronome I also find the different beats fun but that might just be from my XTC days🤪😋🤣

As soon as I started looking at quietening the pumps I thought about a microphone shock mount , you're ahead of the game fella 👍

I learned a lesson when my house got burgled and they ripped the alarm box off the wall and wrapped it in my bed quilt.When sounding off the alarm was deafening but wrapped in quilt you could barely make out a slight squeak.So I simply wrapped my fuel pump in foam strips and tape.It’s done the trick nicely.👌

The sound deadening you have, is intended to remove vibration on thin materials, like steel or aluminum. I doubt it does anything to the plywood. In this case, I guess you would need sound absorption instead.

, wow ! , very smart use of the shock cords!

I like the sound of the pump. I’ve never put it in a box like that.

If you want to keep the hard nylon on the output, you can form a coil with it by wrapping it around something and boil it in water for a while. Remove the core and it will keep a spring like shape. This dissipates a lot of the noise energy and keeps it out if the burn chamber. The whole coil jumps when the pulse occurs, but reduces the ticking noise that comes out if the main air output of the heater.

I have the same result by wrapping the pump in foam and slide that in a piece of 3 inch PVC pipe,

Nice video! Excellent job explaining the details and your thought process.

I described something similar to this to someone having this problem. The only thing I’d change would be to have the pump at an angle (as recommended in the destruction manual) and I’d have the outlet on the top of the box and the inlet on the bottom, to not have the pump in a high point (potential air trap) where air can accumulate. Most of what I describe could be achieved by turning the box through 90° along its long access and installing at the recommended angle.

Horizontally mounted pumps allow permanent air bubble to form at top of pump … the diesel is what lubricates the pump .. the air doesn’t let that happen.. the pump will wear out prematurely

dude we wanted to hear it running !!!!

All this effort to quiet the pumps makes me glad I have mine in a noisy old VW Beetle 🤣

Nice, same technology used on shock cord microphone isolation mounts.

I know the ticking would keep me awake. Great fix!

Great solution. Plywood is a good insulator. The denser the material, the better it'll insulate sound. (Unlike the common misconception that soft materials like foam, etc are good sounds insulators. They're not) As another user commented, the deadening material is used to prevent the vibration on metal in the first place, it is not an insulator. So it should be applied on the metal where the vibration is created. In this case, the pump itself.

That's what I was thinking of doing. Looks like it works like a charm! Thanks!

Good stuff! Thanks for sharing.

Thanks for the video great idea with the box! Just subscribed

, lol ! , don't have one of these heaters , but I wondered what extremes folks go to , just quite that pump down! 😂 - nice little sound-deadening box u made.👍

Nice hack to quiet down the pump!👍

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…..

Nice work.

I have a feeling a lot of what people say about these is bullshit. Doing your own work like this is probably the smartest way to learn. I've been running probably 20ft of soft line for a while now and it was fine the whole time. Priming took forever, but it worked. Mine is in a rubber holder outside the vehicle and is quiet ish, but I'll be looking into this for the future!

I wonder if split cable sleeve or vacuum hose over the nylon fuel line would help with noise.

Carpet works also good for sound insulation

tip that most people don't know: the adhesive sound deadening material everyone loves, doesn't actually ABSORB any sound. All it is, is a dense material that you can easily stick to a surface. Its meant for large flat panels (usually on vehicles) to reduce reverberations caused by vibrations from the road. Think of waving a piece of thin sheet metal around, then doing the same but with 6 layers of duct tape on the center of it. Other tip: covering an entire area in it is a waste of money. Its just there to dampen vibrations, so put a little in the centers of flat areas, and thats it. use foam for the rest

Excellent explanation Thanks

i was thinking maybe you can use the sound foam recording musicians use ,but you may have to modified the box since some of that foam looks to be at least an inch thick

Good explanation to help solved the dreaded tapping curse

to take it to the next level, get a strip of sound deadening and wrap it around the pump

Great idea brilliant just brilliant I thought the samething about the soft fuel line could you please give the information on who and where you got the new pump from. This is the first video on someone coming up with a real solution to an annoying problem I have two of these heaters in my bus conversion imagine two clicking back and forth it's the worst. Anyway thank you for your work here I appreciate your dedication to solving the down fall of this product. Oh I'm definitely sold and subscribing to your channel and looking forward to what other things you come up with.

Great job!

pretty slick

This is amazing.

I have found no literature saying that 45 degrees is any better than 0 degrees (standing upright) so you could just make a box that stands upright :)

So just mount the box at 45 degree's.

Good job 👍

Not sure if the "silent fuel pumps" are rated for horizontal install- but the one the unit comes with- can get air bubbles unless mounted at about a 45 degree angle.

I love the ticking it puts me to sleep

Spokojnie, paliwo też podrożeje 😃

That looks great can you put the sizes of the box you made so I can copy it for when mine come?

I think fuel injection line could be used because its really stiff and reinforced. Only I dont know about the sizing.

If you have a spare pillow or towel and the room wrap it in cling film and tape it job done

Hi does your new pump not have to be mounted on an angle like the original pumps?

awsome idea

Nice work. Fuel pump should be angled down about halfway between horizontal and virtical, according to my eber manual. Probably enough room in the existing box to do that. If do not apparently excessive wear.

Ive built a simlar sort of thing for my pump but it is still slightly audioable at lower pump speeds, Im going to try suspending the whole box from bungee cord to see if it reduces the sound, instead of screwing the box to the outside wall box, Ive mounted my 5kw diesel heater in a wall box on the side of my home and at lower speeds you can still hear the ticking indoors, ideally id like to run it at night on a lower setting say 1.7 Hz but the background ticking keeps me awake at the moment. maybe ill use some screw in brass cup hooks at the top and bottom of the wall box for the heater and some on the plywood pump box and use these to supend the pump box with the bungee cord. Edit: finally found the time today, it works no more ticking in the house at 1.7Hz setting, I attached four cup hooks to the top of the build similar to yours and four more hooks to the top of the heater wall box at the air intake end of the diesel heater. and hung the whole thing on four looped pieces of 6mm bungee cord, Id say the ticking is 97% quieter standing right beside the wall box outside, my neighbours will be pleased as its esspecially quiet around here at night in a rural area in a valley where every sound travels a long way.I realise this isnt very practical for a mobile home or van as it would allow the pump box to swing back and forth but it might just work if there isnt to much slack in the fuel lines.

I'm not an engineer nor am I saying what I am about to mention is correct. This is what I've heard and read many times.. The fuel pump is mounted at an angle for a reason... I see you mounted yours horizontally... I am not sure but you may want to double check to make sure this is acceptable;e mounting... Well done.

Is it burning more clearer if add blue to the fuel line? I've planned to make a t-line joint via the 🚽 of my dear caravan. I fear the lue will maybe stink diesel when rise the lid on toilet? And no matches no more the prevent the toilet smells😢

Your just like my mother, we love her to bits but she takes 15 minutes to explain something that would take most folk 2 minutes at best.. 😆😂

BTW to all the lube ... comments... If you've ever gotten diesel on your hands you know it doesn't just wipe off.. the oil is a super fine oil that once it lubes it's lubed for a while so.. the lube issue may not be an issue at all once the oil / diesel has entered the pump once..

I like the ticking

GREAT video. Important question! Are you also using a BRUSHLESS heater? Are you using a premium brand e.g Webasto, Eberspächer, will a regular chinese be as silent.....does it make any difference? Thanks in advance

That setup, with the pump at the high point is going to trap air, especially w the larger tubing.. Need to invert - but maybe it works anyway? I'm gonna copy your box idea, thanks.

microfiber cloths work well just wrapped around pump

On he pump, is the bore and outside diamater the same both on both the pull side and push side of the pump? Or are they different? For the heater side I know I need 2mm inner diamater hard nylon fuel line. But about the conneting fuel line? Don't know whhat outer diamater is on thhe fuel pump.

What is the Dia. of the pump body?

Nice one, like n sub....Merry Xmas

Quick question… does the diesel heater function well while your van is moving down the road at highway speed?

pump should be at an angle to help lubricate the piston as it is finely machined metal to metal so needs to self lubricate via the diesel otherwise a good silencer method

Just what I was thinking...

Brilliant! Best video I have seen so far to quiet the pump. Obviously some serious and level headed thought taken. Well done! As for the soft rubber fuel line, what is the inside diameter please?

What a great problem

I noticed that the box is hard mounted to your vehicle. Would it not be better to shock cord the box as well.

Can’t find a Webasto petrol 2000 heater sold out everywhere in my search. Anyone?

I fitted mine straight to my van fuel tank the pump is on top of the fuel tank so I don't hear the pump in side the van at all

Do you think the whole fuel line run needs to be rubber? Seems like most of the vibration is on the heater side but only for several inches away from the pump. Otherwise, thanks for the video - I plan to copy your design.

Is your diesel heater a cheap eBay one? Thanks

You don't want it to be late must be angle on it so it don't get air

The only thing wrong is it doesn't have the correct angle!

Use Peristaltic diesel metering Pump

Vinyl mass 8kg man or fill it up with cellulose fibre

All this time and effort and I just went and bought a silent pump of a guy who builds them for £120 and it is silent because it doesn't use these pumps it uses a pulse pump and is adjustable

MDF box lined with Dynamat and filled with soundproof insulation makes it silent.

I don't have any clicking. No clue what I did to avoid that.

Why are they even loud? Certainly they could make a quite pump.

yes, but the ppppump needs to be at an angle

i lagged white pipe with foam

Pump needs to be on an angle, can’t sit sideways. Burns it up. Just set it on a 45.

20 degrees

fuel pump needs to be mounted at an angle of 30\40 degrees

It's supposed to be a 30 degree angle

Sorry flat down must have a angle

Fuel pump needs to be at an angle

It is slient but you did everything wrong, the fuel line, the angle of the pump!

Someone else who doesn’t follow instructions, the fuel pump is meant to be installed at an angle of 45* from the horizontal

6 mins of talking and no demo of the pump operating showing how much improvement you’ve made to the noise???

I run my heater on red diesel it's alot cheaper.

FUEL PUMP PLACEMENT... The pumps are Ch ina Sh it... That is why you re having trouble.

Why not just buy a better (ultra silent) pump?
