I am trying to clean up a fuel suppy issue and wonder if anyone has ran into this issue.
I have what I think is a 71 Block. Has the bigger valves etc. BTW is has a different firing order than most 302’s.
If I prime the pump it will run fine. But if it gets a gulp of air it won’t pull gas. Switching tanks etc.
I have tried running a new line into a tank on floor and it won’t pull unless primed so Not tank issue.
I think it is a bad eccentric or possibly I have the wrong fuel pump? I have a Holley on it that is new as I thought the old one was done. It does work if primed but won’t pull from Dry similar to old pump.
Do early 302’s require different pumps?
Any thoughts?
