I have an '01 w/ a 4.0. I am looking for the fuel pressure test valve but can not locate it. Anyone know which side of the engine it will be on?
Also does anyone know which #fuse the fp fuse is and which # relay. I cant find this info in any books. any help would be great
thanks.

Hi there. Did you ever find the pressure test valve? I have the same problem on my 2001 4.0. I can't find a pressure test valve anywhere. It has to have one doesn't it? Any help would be greatly appreciated. Thanks

yes the test valve is on the passenger side fuel rail all the way in the back. I had to use a flex hose to connect my test gauge to the valve. Good luck!!
