Fuel Fluke

A regulator wouldn't hurt, but an HP carb should be able to deal with 8 psi.

If you want to go electric, and want quiet. Try a Mallory pump. Way more reliable than the holley and *very* quiet too (not as quiet as a mechanical though-LOL). Vane vs. gerotor. The Aeromotive carb type pump is even louder than the holley.

Sometimes its the dumbest things. I had a fuel boiling issue when I got my car. it was because there was a small leak in the manifold by the flapper valve, which is right where the fuel line runs.

Glad you got it fixed.
