    I am planning on running Sniper with EFI tank on the Cuda. I am guessing supply line can be O.E. style and routing, but where have you run return line? Not having car readily available, I can’t check to see if room for running return next to supply line. Could another OE metal supply line be used as a return and would it fit next to actual supply line? If not what/where have you used? Thanks

    There is room next to the factory fuel line. This is where the vent line also ran. You will need a vent line, or vented tank, or vented gas cap. A vent line going to a vapor canister will do the best job of keeping your garage from smelling like gas fumes.

    Edit: the Holley Sniper pick up also has a 1/4 in return line, barbed fitting, built in.
    I would probably make my own steel line and connect it to the vent with a short piece of fuel hose.

    I ran my return line on the driver side since I bent my own line and it was easiest. I also have subframe connectors so they provided a good place to put clips to keep the line secured. I used OEM style 3/8 fuel line for the feed.

    I have Sniper on my 70 Challenger. Used a 3/8 line that was pre-bent for Challengers - real clean installation.
