Hello! Ive got a roller cammed 1957 283 with the factory carter 4 barrel. While in kentucky last august i had some problems with my fuel line. It was actually a hole in the line, but while troubleshooting i replaced the mechanical pump with an electric. Now i really want to go back to mechanical, but im not sure what material or length pushrod to get. I just have a stock style 4-7 psi low pressure pump, so can i use steel? And also, to fight vapor lock id like to install a fuel return line, which ill plumb into the breather hose for the fuel tank (it never works anyway) but with a stock glass bowl fuel filter, how would i attatch it to the carb? What size hose to use?
