Engine/Transmission (1998.5 - 2002) FASS 95GPH limits?

[SKargo]

I am hoping to be close to 400hp when I get on the dyno in a few weeks. At what point is my 95gph pump going to be begging for mercy?



Is there a chart showing flow needed for certain HP levels?

I have similar mods as you and no matter what I do, I cannot make my Fuel pressure gauge to even budge from where it is @ idle to WOT or any other time. 16 PSI all the time. I have read people with problems related to the FASS but I have had ZERO.

I'm 16psi at idle, and the lowest I can pull it is 13psi so I guess all is good?
