1974 Charger EFI Ready Fuel Tank Ideas ?

[451Mopar]

That Aeromotive tank looks like a good deal.
I'm a glutton for punishment. I like trying different stuff. Sometimes it works, and sometimes it don't.

Curious as to why you didn't hook up the 4 expansion tank vent tubes? Is the 74 vent system different from the 71-72? I'm getting parts together and this tank is on my list. My plan is to install it and use the stock lines and expansion tank.

Nice professional wiring on the pump/sending unit btw.

My Charger was born with a 318/904 and from what I could tell used to have at least a 1/4” fuel vapor line running back from the right inner fender. The only thing left was a small tube with nothing but an open end. When I pulled the original tank there were some vent tubes that were not connected so the only vent would be the gas cap.
Since the new tank has an internal pump and return line that circulates fuel just use the gas cap and see what happens. They most likely have to put in some vent tubes so the tank will satisfy any potential pollution or smog issues which can vary from state to state. My car has nothing under there to connect anything to and so far no problems with it. Hope this helps you as you progress.
