Fuel return line?

Mean416 said

Hey. Converting to EFI, and I was wondering about the fuel return. I noticed on the pass side of the engine bay there appears to be a non connected return of some kind. I'm assuming this is some kind of fuel vapor return line? It's a 1972 model.

Any chance I could use this for a return line for the EFI system?

It is not large enough AND THAT LINE IS THE FUEL TANK VENT You can buy aftermarket senders that hae a second port, but it "is known" that aftermarket senders suck for gauge accuracy. If you pull the filler tube you could modify it for a vent and or weld a port in it for the return. or pull the tank and braze a ftting into it. "I thought" there was a thread on here someone installed a return in the stock sender assy.
