Hey Rich! I think isolating the pump and fuel lines: 1) can mount pump and lines with some type of rubber grommet or something to stop vibration from transmitting through mounting hardware. 2) short lengths of braided or flexible fuel line to isolate vibrations from pump to and from fuel lines. Don't know if those are workable ideas, I'm still using my rt's original propane furnace! Heheh
I really appreciate the suggestions. I'm experimenting and incorporating these ideas as I try different approaches. This is really a challenge. I love a good challenge ! But I'm telling you, it's like one of those movies with the submarine underwater and the crew trapped inside signaling topside by banging a wrench on the metal hull. This doink, doink, doink sound can and does penetrate everything I've thrown at it thus far.
Your old Mercedes had what they called a cigar hose after the lift pump. It is a fuel line with a larger diameter section that absorbs the pulses from the pump.
Pretty sure the cigar hose was before the injection pump. I removed several and installed a pre-heater when I experimented with veg-oil and bio-diesel. What reduced the "sound" made by the injection pump slamming fuel in up to 6 cylinders to the injectors in the old indirect injection engines was the shear mass of the injection pipe compared to the pin hole of open space inside the pipe. About a 10 mm outside diameter pipe with less than 1mm "hole" or i.d. inside diameter. I don't know what the psi was through the pipe but it was extreme. Much more than anything these little pumps produce.
I don't personally own one but if it's a problem with vibration going through to whatever you mounted it on. There are industrial pads that dampen vibration, and there are also mini pads specifically made for audiophiles for subwoofers meant to keep vibration going through to your record player even if it's less than a foot away or right next to it. I would suggest these products the industrial you can buy in bulk and some of the audio file ones are big enough to where you can cut it to size. You can also minimize your cost by making platforms with these materials. There are videos on how to make these stands where they take circles of these products and glue them with a strong material on the four corners of wooden cutting boards or other materials how it would go is one cutting board on top four circles of material on each corner below, cutting board again, with four circles on each corner below for feet. When you go to mount it to the top you can also do a rubber pad for grip and to reduce vibration directly transferred to the wood so there isn't a rattle. Wood cutting boards are very cheap and you can even find some good quality butchers block boards.
What say me. Love the propane heater in my van. It will never require maintenance, unless it breaks, it heats the van up quick. It also has a coolcat heat pump. Sometimes I heat it up quick with propane and switch to the HP. I’ve seen a dozen videos of people taking out their propane heaters to put in diesel heaters and I just don’t get it. Some of the reasons they give are miss information or they quote other people and videos that have miss information. Don’t get me wrong. I have a diesel van that I may put a diesel heater in should I build it out and tap the fuel tank. That being said I am looking at another diesel van that at one time had a camper buildout, it has a propane tank. I would probably put in a propane heater before a diesel heater and maybe a diesel heater for redundancy... Maybe not though as it will also likely have a heat pump as well. But what do I know. Just a 40 years, holy cow just did that math didn’t realize it’s been a lifetime now, as a HVAC Contractor.
Time flies when you're having fun, doesn't it? For me it's the availability of power and how much I need to run the propane furnace versus the power it takes to run the diesel furnace. Once the diesel furnace ignites it only uses about an amp of power so I can run it continuously using the battery solar setup I have. The propane furnace consumed quite a bit more battery power to operate and my little solar set up was hard-pressed to keep up. The fuel? Propane versus diesel really isn't that big of a deal.
@@RoadtrekRich I guess I sometimes forget the upgrades I've done that makes it more comfortable. One of the upgrades I'm most happy with are the lithium batteries. They weren't cheap when I installed them, I installed them 3yrs ago I could have 5x the capacity today for the same price, but they've given me a lot of freedom when it comes to powering the rig.
Perhaps "Active Noise Control" (AKA: noise cancellation) could be a solution. Wearing noise cancelling headphones all the time isn't really practical, but there are systems designed for vehicles that cancel road noise, so I wonder if that could be applied here.
Damn ! 3dcritter, You're GOOD !! Yes...you're thinking outside the box ! I'm thrilled to see somebody else doing that. Just a little preview... I have been taking all the suggestions, trying everything I can think of and NO, nothing is really effective...until I did what you did...think outside the box. There are at least two ways to approach this problem. Try to "silence" the pump. OR Figure out a way to camouflage the noise it makes. My next video, in the next day or so, will go into what you and I are both thinking about... ...option or way #2...camouflage. I can say, of anything I've tried, as I said in this video, camouflage IS something I can point to and say "now there's something anybody can do." The materials are readily available, don't cost much, easy to do and understand, and are VERY effective at reducing or virtually eliminating the effect that torturous "doink", "doink", "doink" noise has on, at least me and maybe others as well. Thank YOU !!!! For a BRILLIANT comment !!!
Those are exactly the kinds of suggestions I'm looking for...something that is capable of insulating or isolating the hammering sound. Thanks for the suggestions !!
Hey Rich, check Forestry Forest’s channel. A year or two ago he had a buddy make a box that was supposed to quiet the pump, I think it worked. Did you take out the propane heater in the Trek?
I'll check it out. Thanks for the suggestion. Yes I took it out...saved it...left everything intact from the propane install...fitted the diesel one in the empty space left by the propane one.
Yeah, that's the pump, the guy I mentioned from Sussex England builds. I think that's the ultimate solution...using a different kind of dosing pump that uses a diaphragm versus a steel hammering piston.

Is it able to mount the pump inside the fuel tank like automotive fuel system and use the fuel as a sound insulator?

Dosing pump…
Couldn’t you wrap the pump in some sorta… insulation? Like bubble wrap or egg crate foam …?
Those are exactly the kinds of suggestions I'm looking for...something that is capable of insulating or isolating the hammering sound.
Thanks for the suggestions !!
