I am going to plumb my TBI fuel lines this week. I am using my original supply line as my return line. I have a bunch of 1/2" aluminum Moroso fuel line I can use for the supply side but think it may be a bit big? Does that matter? Should I just order some 5/16's or or other for my supply line?
Also, I have the good ol' fashioned stock 79 tank. I plan to run an inline pump so if it fails, I don't have to drop my tank to replace it. On the pickup, I planned to basically mirror the original pickup (seen below) but with a sock at the end. I plan to have the return line return the fuel over the pickup (basically remove the soft end on the current pickup you see in the picture.
