So, the short version is I'm gonna switch carbs and dizzys from my '76 donor with my '79 pig..The pig has a low mile matched set specter non-usa carb and dizy that I installed not too many miles ago. Problem is, the '76 has a return line off the carb, and the '79 has it off the fuel pump. Do I switch pumps too? And the donor '76 engine will be transplanted into my '66 fj45 soon, and it has no provision for a return line into the tank. I'm thinking I should either run an electric fuel pump to the '79 carb with no return at all, or plumb a fitting into the '66 tank for a return..... confused? I am... and whats up with black type?
