Car struggles to make fuel pressure

Mitco39

Charles, I swapped out the pump with the aeromotive 340 so its got a brand new good pump in it with 10ga running all the way back to the tank.

Its so bad that when heat soaked and hot it struggles to start. Cold it fires up just like stock. I will get another regulator to try while im down here if I can find a place with one. Makes me wonder if I should be mounting it somewhere away from the heat, although there isn't many other choices on our car. The other thing I can try is setting the idle pressure with the system hot. That means however that it will idle at a much higher fuel pressure when colder.
