Fitech

I am running the Fuel Command Center. many people talk **** about it, but mine is the Gen1, still going strong. It's just a surge tank. It's easy to install. Mine is right where the horns originally mount. I went the FCC route because I originally didn't trust the Fitech, so in the trunk I kept my old holley and a fuel line. If the FitTech crapped out on me, I could simply swap the throttle body for the carb, throw the fuel line on from the mechanical pump to the carb, and head home. I never intended for the FCC to be permanent and if/when it ever fails, my plan is to go Tanks Inc with submerged pump.
I also strongly suggest using a much better fuel filter than supplied with the kit, and using an external fuel pressure regulator. Your system won't use 58psi, off the top of my head it's 43psi..
