Fuel system upgrade on my 2000 Camaro SS
I recently am in the process of installing an entire fuel system upgrade for my 2000 Camaro SS. Tank is still out. I went with the following:
-The QFS-A447HV is a direct drop-in 340LPH.
-SS tube Quick Fix braided lines
-Racetronix Fuel Pump Harness MP150S-4M > GT280S-4F ---- Fuel injector clinic 45cc (50 lbs/hr at OE 58 PSI fuel pressure) fuel Injector Set for LS1 engines (High-Z) (is301-0445h)
I discovered that the previous owner was running boost at some point for there is an old style Vortech fuel management unit installed in the engine bay and an additional fuel line was ran to the end of the front end of the driver side of the fuel rail. Also a secondary piggy back fuel pump installed toward the back of the car. The in tank fuel pump is stock. I am removing all of this. The dilemma that I am having is that the stock T fitting system is gone so no return for the pump at this time. I was considering going to a C5 fuel filter / Regulator system like a WIX 33737. Quantum makes this style too. I have heard with this setup the regulator can not handle the high flow fuel pump and it will cause fueling spikes. I have seen mixed reviews about this but this would be an Quick system for me to hook up. Once this is sorted it will be tuned by black bear. My current mod list.
