Default fuel flow/pressure question

I have my volvo conversion running, and it seems fine with the stock pump.
After working thru some bugs, I now have no codes.

How do I know, besides burning a piston, if I'm short of fuel pressure?
Would it set lean codes?

1. Check the pressure to begin with.
2. Data log the fuel trims, O2 readings, etc.
3. Put your fp gauge up on the w/s and drive the car. See if your pump keeps up w/ demand.

1 - don't have a fp gage, did the reserch and found out the volvo worked on the same pressure and went from there
2 - don't have a way to log the fuel trims etc, just have an obd II reader.
3- see 1 above.

guess I should buy a fp gage and a hose that I can read thru the w/s.

there's a port on the fuel rail, can I connect a gage line there (who makes that fitting?), or do I tee into the flex line that I have between the car and the fuel rail and do it with soft line?

after dealing with all the big stuff, now I'm killing just as much time on the small stuff. Still have a rats nest of original wiring that I don't want to cut until all the little stuff (fans, ac, cruise, etc) is sorted out, but I'm at the point where it's time to register the car and go for a real ride....
