I have a 64 valiant that was a /6 car. I am installing a 5.2L magnum with crosswind intake manifold and carter AFB carb, I will be using 70’s passenger car front accessories, stock magnum camshaft. I am trying to decide on what fuel system to use. I have a new in box mechanical fuel pump, I have read mixed reviews on the fuel pump eccentric. My other concerns are my car has 5/16” fuel sender and feed line. Am I better off installing a electric pump at the tank with a new 3/8s fuel sender and installing a regulator with a return line to the tank? Or is the camshaft eccentric with mechanical pump and the stock fuel setup sufficient for the 5.2L?
