Default Adding fuel return line

My lemans didn’t have a fuel return line. I’m am going to use an MSD atomic fuel injection throttle body, and a robbmc surge tank that requires a return to the fuel tank

I am mounting the surge tank next to the charcoal canister on the passenger side radiator support. I’d like to retain the vent line to the charcoal canister

I’ve heard that I could use a chevelle fuel line down the passenger side, but I would have to lift the body off the frame to install it. I don’t want to mess with that because it is a convertible and all of the body panels line up really well right now.


I was thinking I might use the existing vent line as a return and then run some sort of flexible line for the vent. It’s a low pressure return, but I want to make sure I don’t have a safety issue. Does anyone have any suggestions on the best way to do this?
