Engine/Transmission (1998.5 - 2002) Diesel-Dan, I have a FASS Question

[JField]

I just installed a Fass 95 in my 98 24V and am only seeing pressures of 9psi

at idle and will go down to 0 under full throttle. I have verified my guage accuracy with another guage. I am running through through a prime-loc filter system, but even with a 4psi drop through prime-loc the pressure isn't good.

My question is, What pressure spring comes standard on the Fass with filters, and what spring # should I get to raise my pressures to a constant 12 to 18 PSI. I've yet to pull my 5th wheel and am concerned with my current fuel pressure. Any Thoughts?

Do you have the 95/95-1008 or 150/95-1008? Where are you reading you pressure at?

 

[JField]

I have the 95, and sending unit is on the test ports on top of where the fuel filter was originally mounted.

Also, after you've spent almost $700 bucks for the pump, you think they would throw in a spring kit that includes 2 to 3 springs so that you can adjust and get the pressure you want to run .

Diesel-Dan,

Thanks for the quick reply. Its always good to get help when you need it. Especially when its from a fellow member who is also "THE Spokesman" for the company I bought this thiong from.

Any possibility of a pinched or crimped line somewhere in the circuit that's restricting the flow?
