Hello All, I just installed a 150/150 Fass system on my truck last week,due to failing lift pump. My problem is I am only getting 5-6 PSI. Any suggestions on what I should do?

Check the spring under the fitting that returns fuel to the tank... see if there is one in there?? They have several different springs for the 95s, not sure about the 150s... almost sounds like the check ball /spring were not installed or they are not seating like they should.



Do you have a restriction in the tank I wonder?



Maybe double check your guage reading against another guage?

Thanks, Steve I'll check that tonight! Also forgot to mention I checked the Gauge already and it's fine. But I will check on the spring and the restrictions. Thanks again.

Well, I found the problem. It was a simple one at that. All that was wrong was there was a kink in my plastic fuel pressure line running up to the gauge. I found her under the dash ( little stinker ). Thanks for the help!
