Fuel system recommendations
My 2011 c6z has a faulty one way valve giving me a hard start condition. I’m changing the clutch in a few weeks and figured I’d address the pump.
Car made 555 rwhp on pump gas with below mods:
AHP heads
Custom Comp Cam 241/248; .661”/.652” 114+4
HPR dry sleeved short block 12:1 compression
AHP ported stock intake
stock exhaust
stock CAI
installing
Tony Mamo atomic intake
NW TB
SLP CAI
ARH 2” headers with catted x pipe
FIC 660 cc injectors
DSX flex fuel to run E85
hoping to make 625 rwhp but the car will never see boost or ever be pushed passed 700 rwhp. I have a 1250 rwhp c7z for that itch.
what fuel system makes the most sense?
currently considering the fore dual pump setup or racetronics 525lph drop in unit. I’m definitely open to suggestions.

We use the 525 and 485 pumps from Walbro ALOT and both work well.
We sell more of the 525 pump than any other pump. you do have to modify the bucket a light bit for either pump but its simple and works well.
Just my 2 cents
