If I can get a hold of Ron Schwarz, I will ask him his thoughts on our problem. He does not get on here often.

Is it sucking air are getting hot? Is that a race pump and not made for street driving?

lol, musta been a lot of Miller Lites Some quality homebrews get you to that point alot quicker

Ok, here is an update: It's not electrical. I spoke with engineering at Holley. The first pump I sent back was seized mechanically. They are thinking it is cavitating or straight up sucking air. He explained they are fixed volume pumps and move alot of fuel. They can create the "toilet bowl effect" -you know how you give a swirly That would make sense if you were just driving along with minimal sloshing. So I'm thinking I need to do something with the pickup inlet. Also, I can't see how the return line interacts with the pickup, hopefully its not pointing right at it or that could cause aeration too.

here is a shot of the pickup tube removed and placed directly above where it is mounted. Notice the slash cut doesn't point down, but more forward and up just a bit. Hmmm


hard to see but just above the writing on the tank there are three spot welds, that is where the baffle wall is that the pickup tube goes thru.

No need to call the big shooter in yet! I'm sure Ron could figure out the electrical gremlins though. I saw him in action at Kershaw on Tom's car, lol

Thanks Payton.
