I don't plan on throwing parts at the car.

Gauge bleed valve? My fuel pressure gauge doesn't have one.

If there is air in the system won't it eventually burp out?

There is no visible sign of gas or any fluid in the vacuum line from the fpr. It smells like gas but after turning on and off the ignition I did not see any visible sign of any fluids. I will start the car with the line off and see if that makes a difference regarding the presence of gas or not in the line.

Also when pinching the braided fuel lines, are you pinching them with pliers or such? Are you wrapping the braided line with a towel or something to cushion the braided line?

I just came back from a 20 minute joy ride. Drove to my friends shop and he was not there yet. Wanted to use his fuel pressure gauge to double check mine.

Seems like my car is possessed. It drove fine. No bogging or poor running conditions. Plenty of pull power, etc.

Hopefully my old fuel pressure gauge and or air in the fuel line was the problem.

Going to work now and will see what happens tomorrow and during the weekend.

Its to nice outside to not drive the Z!

Sounds like FPR is good, with no gas in FPR vac tube. Now you need only to check for injectors leaking...

Fuel pressure guage should have a button on the side that lets fuel drain, so you can remove it without fuel spraying. Maybe some don't have it.

I pinched the fuel line with Vise Grips. CAREFULLY. I always preached against this, because of damage to the line. But FSM suggests this. A rag might help insure against damage. Pinching does deform slightly the braided line, but you can squeeze it back with your fingers.

I don't know if air will 'burp out' or not. I had air after top end work, and I wanted it out before proceeding.

Did you save your old pumps? Sounds like they were good...
