Fuel Pressure Question

AirDog or AirDog2? Stock VP44?
Either way, 150gph should be just fine to support 125's.
Definitely get Gauges! Lift Pump to VP gauge should read between 0-30psi (a select few might argue higher up to 50psi, but you're playing with fire. The AirDog should come preset regardless of which model you got around 15-17psi, but please be sure to check it rather than assuming it's spot-on, as the VP's are very particular about their incoming psi in order to keep working properly).
Also, get a gauge that goes to 30k, reading psi after the VP.
I would highly recommend a low Lift Pump psi indicator, either an alarm or light, via AirDog pre-wired harness or on a gauge (some Programmers have capability), to quickly bring to your attention if the lift pump quits pumping optimally or completely, for an array of reasons like pump motor failure, shorted wiring, filter plug, etc. It's inexpensive security preventing being stranded, or shopping for a bbq VP.
