carhauler- my truck has 12. 5 psi at idle,5 psi at wot (in a extended run not momentarily) and all the guages I have are Auto Meter ultralites

 

[carhauler]

so autometer makes fuel pressure guage in the ultralite.



Does it come with all of the fittings to fit our trucks

 

[Blackcloud]

mine did--you'll need a adapter line to come off the schrader valve on the fuel filter to go to the pressure sensor that comes with the guage--the adapter line I used was a old end/section from a junk set of freon guages I had laying around,it works for me
