2003 workhorse P32 fuel pressure
I installed a max tow fuel pressure gauge and see I'm only getting 46 psi. Can anyone confirm that all 8.1 vortecs should be 58-61 psi? I've already changed the fuel filter and that made no differe...

Thanks for the info. I'll look tomorrow for the regulator.
Yes, I have been having trouble. I had trouble with a clogged fuel filter, changing it helped but still have intermittent issues with it loosing power. I step on the gas to accelerate and instead of reving, the engine nearly dies. (No check engine light). I haven't driven it any distance since installing the gauge but I'm curious if I'll see a further drop in fuel pressure when that happens again. I also have a scan gauge conected so maybe that can shed some light as to what's going on.
Thanks
