I own a 1973 Chevy cheyenne C10 long bed 350engine with th350.i want to add a fuel return line to help with vapor lock and to keep the mechanical fuel pump from boiling the fuel.my truck came with a 2 line sending unit,1 line to the carburetor and the other line to a charcoal canister.my mechanical fuel pump is also 2 lines,1line to carburetor and the other line to the fuel tank.
Can i change my sending unit and mechanical fuel pump to a 3 line fuel system?
I know there are kits out there that can create that return line i want but i dont want to drill into my fuel tankany help with my issue will be very much appreciated.
