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.

 

Big line kit and holley 13 psi idle and i have never seen it go below 9psi I have hot juice too power level six. mario

 

I know you already know mine but:
Holley Black
Vulcan Big Line Kit

Idle: 10.2psi
Cruise: 9.2-9.8psi
WOT: 8.6psi

Will update once I get my new sender installed too.

 

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.
