I have the engine out and started cleaning up around the engine compartment. I removed some thick, dried out black gunk impregnated, wrapping around the fuel lines where they run from the firewall to the engine shelf. I guess the wrapping was for protection. Anyway, under the wrapping I see that the return line is plugged with a screw. The fuel line runs to a filter under the shelf, then to a cheap-o (but works) regulator in the engine compartment, followed by another filter, then to a T, and finally to the carbs. I have no idea what the plumbing is under the fuel tank in the front. I have carbs, the fuel pump is in the front, and the engine runs fine. Should the return line be operational? What is its function? I am guessing it is related to FI and not carbs.
