Re: 6.0 runs and quits

One time on a C4 Corvette I added a big Aeromotive pump and then wound up with too much fuel pressure because the factory regulator didn't actually flow enough to "bleed" all that excess flow back to the tank...

Point being that insufficient or restricted returns can cause too high of pressure.
