I put a EV2 fuel pressure gauge in the truck when I installed the air dog. It was pulsating. So I bought a autometer snubber over the weekend and it controlled it for 45min and now its pulsating again, any thoughts?

 

Is it a snubber for diesel? they make them for gas and air as well.

So the gauge quit working or you are getting pressure pulses? If its pulses, you could install a needle valve and run it barely cracked.

 

It is for diesel. I was thinking needle valve next. Its pulsing.

 

You suck... You are horrible... You are probably racist... Your mama wears boots...

Oh, not that kind of "snubber."

Try one of these in the line before the gauge. Use whichever one works best for your application. Adjust it until the needle sits quiet, then lock down the packing nut to make sure it stays adjusted (tighter the packing, more difficult to move the needle). The way the fuel pumps work on most Cummins will tear up a gauge in short order.
