Fuel pressure gauge

Good, I was afraid maybe there was something wrong with my ip. I put the gauge on with a new lift pump.
How did you mount your gauge?
I ended up buying a cheap bracket from Isspro because they said it would snap right in and wouldn't need a retainer on the back of the gauge. Not the case.....I could have went to Auto Zone and bought the same bracket for for $5!

This whole thing started because he got a new FASS lift pump. That doesn't mean the pump isn't bad, but all those pressures sound way too low to me and even the best gauges aren't completely without defective units. If there's any way you can put a mechanical gauge on to get a "second opinion", I'd want to try that too. It's easier to change than the LP, but regardless, you have to try ruling them both out. Usually when FP sensors go bad they go the other way, showing higher and higher pressures until they're spiking out the gauge, but that doesn't mean you don't have a bad sensor. If you still have your stock LP and it works, you could swap it back in to check that too. Either way I wouldn't pull again until you figure out which is the problem. If it's the gauge, great; but if it's not... you don't want to screw around with under-feeding a VP44.
