FiTech EFI system

Both the command center, and a pump will require a line back to the tank. The FCC just uses a "vent" opposed to the constant return of the inline pump.

It'd be very easy to just swap out your current regulator, and inline pump, and just run the return type external pump. Unless you want to get into something as extravagant as an aeromotive drop in sump or tank.

Using the fcc with an existing electric pump seems double redundant to me...

very easy to just pop a bulkhead fitting in for a return.

I agree on the double redundancy. It doesn't seem right, but when the shop built my car with the carb on it, for whatever reason the pulley system they used couldn't accommodate a mechanical pump. I'm currently running a Holley Blue pump. I'm trying to keep the work, cost, and parts used/removed/replaced down to a minimum. Based off of their instruction manuals, it seems to make a little more sense to go from tank, to electric pump, to throttle body, and back to tank since I already have 90% of they system in place.

So, Fitech's frame mount fuel delivery kit could be used as a return line? Do I need a pump for the return line? Where on the tank would I return it to.

Sorry for any ignorance. Carbs and fuel injection are still a little new to me, but reading the instructions, EFI doesn't seem too hard and will get my car to how I'd want it to be.
