2nd Gen Non-Engine/Transmission Fuel Pressure Gauge ?

[JTHosler]

Hello all,



For the past couple days I have noticed my fuel pressure gauge has a twitch for lack of a better word. It twitches between 12-15psi at idle then smooths out 14-15psi at cruising speeds. When the FASS was installed we put a snubber in to get rid of the bounce it had with the stock lift pump. Any ideas of what is causing this, or how to resolve this problem (twitch)?



Thanks in advance,

The only solution anyone has given me, was to put a larger fuel pick-up in the tank to get rid of the needle twitch on the fuel pressure gauge. I was wondering if it was a bad gauge or isolator. Any thoughts?



Thanks,

Justin

Where are you tapped into to measure fuel pressure?



What type of line are you using for a snubber to your isolator?

I am measuring pressure going into the vp. The line going to the snubber is the line from FASS. I hope that makes sense, I did not do the install.
