So far so good.

Good to hear you have this resolved. Moper was right about the fuel line routing as it would leave a bubble of air in the high spot which whould make the pump cavitate. Just like vapor lock, but not caused by heat. The previuos owner must have used the electric pump to try to overcome the problem.

That's what I figure.

Could it have something to do with gravity and the fuel being siphoned back to the tank working against the pump?

I guess so... the pump couldn't pull the fuel up the hill after everything got warm.

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.

The pressure today was in between 7.5 and 8.

I'm going to try and run it without a regulator.
