@10MickeyMouse thank you for the information

Two things: One, be sure to know whether your fuel pressure specification is key on, engine off (KOEO) or key on, engine running (KOER), as they will be different readings. Secondly, be sure you're connected to the fuel pressure test port and not the evap port (usually a green cap or tag).
Also, not all vehicles have a schrader valve test port. Most domentics do, but Asian and European cars typically require adapters and removing the fuel line or hose at some point.

Some people put Teflon tape to stop the gauge from leaking fuel in the test. What my question is do you use the tape bye warping it around the treads of the gauge before its screwed in or is there another way?

i just bought that gauge. does it work well? do you think it would last. i know some people said the gauge fills with gas. I was wondering is that because something was done incorrectly?
