I was hoping to check my fuel pressure to make sure it was up to specs. Can someone clue me in to the location of the schrader valve ? This is my first I-6 powered truck I have owned. I must say I am inpressed with the nice flat torque curve.

On all EFI Fords I have owned the fuel pressure is usually lower than what the book calls for. Its probably due to the spring in the regulator getting a little weaker as the years go by. Whenever I get a new used Ford I check the pressure, and if it's low I give the regulator a little squeeze untill the pressure is where its supposed to be at.

 

It's on the rail just behind the #6 cylinder. It's all the way back by the firewall, just to the passenger side of center. You'll have to feel for it because you won't be able to see it.
