2nd Gen Non-Engine/Transmission Snubber

What is it and where can i get one?

It is a buffer between the fuel pump and a fuel pressure gauge to prolong the life of the gauge or sender. It dampens the hammer effect of the pump from what I understand. Some people use a rubber 18" grease gun hose. The rubber takes some of the energy that would otherwise be transferred to the gauge. I have a mechanical gauge without an electric sender. I just leave the gauge hose full of air when I hook it to the pump. The air cushion has worked well for me so far.

Several make their own. A snubber is nothing more than a device to limit flow. Typically on a fuel line before the gauge to smooth out the pulsations on the VP side or to limit the damage from a line break if you use mechanical gauges.



Generally most put the gauge ona 18" hose, like a grease gun hose etc about 18" long. Bill Fleming came up with the idea of using a needle check valve like you find at a plumming supply (like the kind on the refridgerator water ice maker lines).



I use Bill's idea.



You can also fins actual snubbers which are like a porous material that will let the pressure through, but the fluid has to weave its way through the porous material and that limits a high flow rate problem.



Hope this helps,

If I remember right I got mine from either ISSPRO or BD Power can't remember for sure and too lazy to dig out the file and dig through my records or I could tell you for sure.

Just buy a 1/8'' needle valve from any place that sells plumbing and run it almost all the way shut, set you back less than $5.

Advantage of a needle valve over a snubber is that you can shut it down if you ever have a leak.
