I just had an odd thing happen where the fuel pressure dropped to 20. Don't know if it is the pump or regulator, but thought I might get recommendations on what to pick up next time, or as spares.
I need 50 psi at the injectors, it is a stock 5.9 magnum, so no high hp stuff needed.
I am currently running an aeromotive regulator, return style and a MSD fuel pump.
update: a bit late, but didn't realize this was out there.
I found out what the problem was.
when I put this together, there was no exhaust in the car.
So I mounted the pump on the rail just infront of the rear wheel.
dork that put in my exhaust, routed it right up against the fuel pump.
I couldn't even put my hand between the exhaust and the pump.
so when I would sit still or idle for long periods of time, it would overheat the pump to where it basically shut down. or gave me that 20 psi.
once it cooled off, it ran like normal.
I replaced the pump just incase the damage was done, and remounted the new one over the rear diff, above the tank so I wouldn't have this problem again.
