Fuelabs pump issues

[572Camaro]

John is exactly right.
How is your tank vented?
When the pump air binds, pull your fuel cap and see if the fuel tank is in a vacuum condition.
What is the fuel pump inlet hose/tubing size?
I hope it’s a minimum of 1/2” diameter

Once we figure out root cause, please consider mounting pump in tank so long as it is submersible.
In-tank pumps are quieter, run cooler, and eliminate undercarriage clutter.

(I run Aeromotive pumps in tank and have no regrets. My car is “Jim and Geralyns Camaro now on lat-G car features)
