Can a stock fuel pump produce too much pressure?

With the Holley, I pulled the needle and seat and replaced it. It seemed to run the same. I removed the side plug in the float bowl and fuel drained out so I adjusted the float setting. It still seemed to puke out the vent tube.
The ThermoQuad does the same thing. The ThermoQuad has maybe 15 minutes of run time on it since it was rebuilt.
At least a year ago I decided to tinker with the car a bit. I couldn't keep it running because I wasn't getting fuel up from the tank. I went to the shed and grabbed a shiny looking pump and swapped it in. I have collected parts from friends and acquaintances for years and often times, I don't remember where a lot of this stuff came from. I don't recall any special markings on this one to denote any high volume design.
I have a few other cars here with Holleys that all run great. I can pull carburetors off of any one of them to test on the Duster.
It was 111 when I was out there working on the car. Usually I think of trying parts from other cars but maybe the heat was getting to me.
