It's time to run the fuel line in my FE equipped older Contemporary that I'm restoring from the frame rails up, and I'm not sure what size fuel line to run. I have the sending unit / pickup out of the tank and I'll have the pickup line changed out to match the size fuel line that I end up running. The engine is a 600+ HP 482" sideoiler, with a single 900 CFM Quickfuel carb. I'm running two Facet blue dot electric pumps, each has 3/8" fittings. It's easy to just go with 1/2" line and play it safe, but it's bulky and more difficult to work with, and in such a small car it gets tight in some places. Do I need the 1/2" line? Does it even make sense to deal with the 1/2" line with the pumps only having 3/8" in and out fittings? Also, is there any reason to run a mechanical pump as well? If so does anyone have a recommendation on a mechanical pump that will have the correct size fittings? Thanks.
