I recently dropped in a fresh engine into 90 GMC. It's a .030 350, with flat tops pistons,268H comp cam,vortec heads, edelbrock performer rpm air gap intake and a 650 Holley spread bore carb. I installed a new hei distributer and have the wiring figured out. What I need to know is, does the fuel pump circuit have to be rewired ? If so ,how? Thanks in advance.
