54lbs rail pressure?? Isn't the fuel pressure supposed to be 58lbs? What's the flow difference over 4lbs?
My gauge was reading 54lbs all afternoon yesterday, Just installed it.

Weird. I just installed a fuel pressure sender and it reads low to mid 60's until I get around 4psi and it starts to drop to 59-61psi until the second pump kicks on then it goes back up to 62-65psi.
Typically a good pump will make about 60-62psi at idle. It will drop back to 58 under load, which is normal.
If you have low idle pressure, you could have a bad gauge, a poorly installed pump (generic kits with rubber hoses often leak), or a problem with the pump you are using.
Does it hold pressure when the car is not running?
If not, you likely have an install issue.

What kind of gauge? I have a mechanical gauge on my regulator and an electric gauge with the sender a little further upstream...there's about a 4psi difference between the two at all times.

I'm using an Autometer electric dial gauge. It sits at 54# constantly. And the sending unit is right at the rail crossover.
I've got a Racetronix 255 with the hotwire fix. And knowing the *** stick/hack that installed it, he MAY have fuked something up. I'll have to rip it apart this winter and see WTF is in there. If he installed a BBK against my consent, he'll get a brick thru his window.
Trying to argue with him is pointless and he won't reimburse anyone.

Sounds like a calibration variance issue. Personally, I'd trust (and do trust) the autometer electric gauge.
