The more I review the test procedures, the more questions I have. I can understand how you can test full fuel pressure from the pump. I can't understand though, with the gage connected as directed; how you can read running fuel pressure since the connection is prior to the pressure regulator. Maybe I am not seeing the setup correctly. Thoughts??

All the fluid inside the line before the regulator will be the same, regulated,pressure. The line after the regulator is just the return.

Thanks, must be one of those physics things. Like lift, you can't see it, but you know it's there, and it works!
