First off, curse whichever engineer placed the o2 sensor on the passenger side tucked up where you can barely get at it with your fingers, much less with a wrench. Finally broke it loose and replaced with GM Parts Direct sensors. It looked like they were due anyway based on all the rust and corrosion on them.
Anyway, I've been doing some more reading and apparently the fpr I bought covers a range of vehicles (anywhere from 2.5 bar to 4 bar+) and I need to set the pressure via the torx set screw on top. So if I have to set the pressure am I better off setting it towards the top of the range?
I checked voltage going to the pump at the relay before dropping the tank and had just a little over 12v KOEO. Need to recheck with engine running, but think I'm good for now.
