    Just wondering did a 73 Roadrunner with a 400 come with a return fuel line, and if so where does the return line hook up to under the hood. Is it a different fuel pump.
    Thanks.

    Since this site was originally for the '69 Road Runners only, that is what this sites manual is for. No help for a '73. I can't say for sure, but try going to www.mymopar.com They may have something there or you could try doing a search to see what may come up.

    I have a 74 manual that I got with my 73 /400/ road runner when I purchased it. It should be the same. I will look and see if it has the info in it that you are looking for if so I can post some pictures for you. CF1A066B-CCD6-46A4-95B0-EB72D53DB11E.jpeg 160A36E0-E33A-4913-8F61-ADE199D96EF8.jpeg

    On my 68 it's a vent/fuel vapor return, not a fuel return. Here's a picture of Bob's engine. Black canister in front of fuel pump is a "fuel vapor separator" mounted correctly. If I get your question right, fuel line from pump to separator, from separator to carb, smaller tube on bottom of separator to second vent on fuel tank. (that is if you have two vents on your fuel tank) I had to ask the forum about this about a year ago and of course got led in right direction.
