This is a computer controlled, variable pressure system. It has a pressure sensor and a fuel pump control module along with the Powertrain Control module that all play a part in it. You need a professional scan tool to be able to diagnose that system.

You really need a scan tool to test that system. You can command it higher and lower and you the gauge to see if it responds properly.
