hello all, Ijust got done installing my new PE 4200 fuel pump and high flow banjo bolt and my pressure is a rock solid 19 psi @ WOT and cruise but 25 at idle. I wired the pump on a double relay(for high amperage) and the ecm controls the signal so hard starting is not an issue.I was wondering if there are any ill effects to high fuel pressure or dose it not matter?This is all in preperation for my new Doms EDM mach 2 injectors. any response is great.

WOW...25 @ idle? dang, that's amazing i bet those Mach injectors will suck down that gauge a bit

 

I've seen reports of hard-to-start troubles when the pressures were over 20psi.
If yours is starting OK you should be good to go.

 

I've never had a VP44 problem while running the PE pumps on several trucks. The PE itself though.... well... it's had some issues. I'd highly suggest carrying an emergency pump in the truck.
