I plan on installing a Fuel injected v8 in the C-10, which has a 6 in it now. Anyhow, the FI fuel return line is the question: I plan on using the original gas tank and making the original fuel line from it the F.I return line, and then adding a new, 3/8" line soldered into the tank as the F.I. fuel feed line. Has anyone done this before, and if not, how did you approach the F.I. return line matter ?
