After running around the internet and seeing all the weird tales of fuel pressure... I desided to make a quick video of what my truck does with...

AirDog 150
Edge Comp (5x5)
Stock Injectors

Conditions Fire up... Get out to the highway and row out the gears up to 75 MPH. Fuel pressure gauge is in the center 15 PSI is straight up and the first tick mark you see to the right is 17.5 PSI.

(Might be better to visit the Youtube page - http://www.youtube.com/watch?v=grl72Up-8T0 )

I idle at 17.5 PSI and WOT at 15.0 PSI @ 75 MPH.

This is a fail!

Wasn't meant too... It just the check ball and spring problem in mine. After a period of time the check ball is shoved down into the coils of the spring and then the pressure falls. So I take the time to clean it up and reset up the pump again...
