I ran my car at the local track last night, and my car fell on it's face on my last pass when I grabbed 3rd gear. Looked at the logs, and I was losing fuel pressure (about 15 psi drop) after roughly 6k RPM. Never been a problem before, but I was probably around 1/4 tank of gas or a little more this time. I don't like running much below half, but I figured I'd be fine at 1/4 tank with the factory sumped tank. I am running a return style system with a Division X fuel hat and twin Aeromotive 340 stealth pumps. Do people have problems with 03 Cobra fuel tanks and starving the pumps?
