Fuel pressure and Big line kit.
 
Well my stock LP went south finally so i deleted it and ran the big line kit to the FF and then to the VP44.
Running the Holley blue i am seeing 10 idle and 6 WOT comp on 5x5. When the LP and Holley were running i was seeing 23 idle and 15 Wot before big line to the VP44.
Is the big line kit responsible for the lower FP readings but now i have more volume to the pump?
So what are your pressures with your big line kit and Holley? Not FASS or Walbro.

I just got my fuel system fiqured out, It finally has good pressure, 25psi at idle and 20 WOT comp on 5x5. I have a holley blue on the frame and a carter 4601HP in the stock location and a big line kit, works great.
