With both my edge and bully dog on their highest levels I am losing fuel pressure at the rails. Was wondering if anyone has done any experimenting with inline fuel pumps other than the Fass fuel?

I run just a off the shelf holley blue pump, that i plumbed and wired in myself, i could always maintain atleast 20k of rail psi. 20k still is not ideal but its alot better than say 12-14k!

Was wondering if you use the fuel pressure regulator that comes with the pump and what it is set at?

THey are self regulating @ 14psi, that is fine for most lb7 engines, for a lly i would cut it back to about 10psi. I just pulled the spring out of the pump and kept cutting bits off at a time untill it ran @ 10psi!
