I'm looking to upgrade my pump since I'll need more fuel for the holley efi I'm going to be running (58-60psi required). Holley gave me a few different part numbers that would work with the system but I'm not sure how that would connect to the gas cap filler plate attached to my current setup? They have an option for just the pump to install on the factory hanger as well to avoid this issue but I believe the lines on the factory hanger are to small (5/16") when they are saying I need 3/8" minimum. I plan on running new 3/8" line from the pump to the motor but not sure what to do about the hanger situation. Does anyone make aftermarket hangers with larger lines that also has the gas cap port built in?
