Engine/Transmission (1998.5 - 2002) Fuel Pressure Guage Vibration

[wes reeves]

I installed a mechanical fuel pressure guage yesterday and have been trying to get rid of the vibration that came with it. It's plumbed through a braided stainless steel line from the VP-44 to the guage on the A-pillar. I started trying to cure the vibration by putting 3/8" rubber fuel line around the stainless line anywhere it touched other parts. That helped a little, but it vibrated. Today I insulated the entire line with rubber fuel line and clamped it down to the body in a few places and it helped, but not much. I don't really want to, but I'm tempted to cut out part of the stainless line and a add about a foot of rubber hose to see if that helps.



If anyone one can give me any other suggestions they would be appreciated.

take the pressure from the bottom outlet of the fuel filter, works great with less pulsation

yep, the pulsation is from the vp44 go around the fuel filter area and your pulsation should go away

I ended up getting rid of the vibration by using a different fitting going into the back of the guage. The first one was touching the guage pod and vibrating the whole pod. I wrapped this one with rubber and made sure it's not touching anything and the vibration is gone.



Thanks for the suggestions though.
