Ive got a 150 HPFP on my 00 cummins and it isn't keeping fuel pressure up where it needs to be at WOT i can drop psi down to zero. Is there a spring that i can change in this pump. I also have a 05 cummins and that has a Fass 150 w filters. If there is nothing that i can do to increase the pressure on the HPFP could i put the HPFP on the 05 and the Fass on the 00 and everything be ok.
