Car struggles to make fuel pressure

phunk

Fuel heat can definitely cause problems but considering you are returning before the rails and only running a single pump, you are hardly pushing it as far as fuel system work goes and things that contribute to fuel system heat. I dont know what the weather is like there and if you have a vented hood or not, but you could always try reducing heat in the bay, heat wrapping some things, etc, and see if that helps your case.
