FiTech EFI system

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.

This is the photo I'm referring to on their instruction manual:

You remove the blue pump and carb regulator, and any line that isn't 6AN,...then Use the pump kit i pasted above to replace it.

I don't know how they have your line coming out of the existing tank, or if you have a factory sender still in place, but you can send the return fuel into one of the barbs that is currently not being used...or even the base of the filler neck.

i assume you don't have a sumped tank? The "right" way to do it isn't really for a factory sender to be supplying the uphill fuel to a pump like this...but alot of guys make it work, and are fine with this pump kit.

The line and fittings you already have can be used AFTER this pump if its 6AN...or most would use it as a return line, only if you need "extra"...and again that assuming its 6AN.

does that make sense?
