Would like to check fuel pressure with a mechancial gauge at oil change time not perminent. Is there a schrader valve on these trucks? I have look and searched but no results. Or is it a matter of changing a fuel banjo bolt and adding schrader valve if possible?

 

Glacier diesel has banjo bolts with FNPT so you can connect whatever you want. Craig

 

Either add a tapped banjo bolt at the CP3 or a billet fuel filter cover from Genos to tap for fuel pressure.
