I'm about to re-oring my FPR and I'd like to shim it if need be while I'm at it. I've tried two different tire guages to check the pressure. One is a 250 psi heavy duty and the other is a 120 psi stick guage. Neither registered any pressure although the valve was peeing diesel everywhere. The truck runs well, could it be THAT low? I've heard a bunch of guys say that they used tire sticks. A little advice please...

 

I used a dial gauge, but I'm sure I've read others used a stick gauge. How low do those gauges you tried go?

 

I used a fuel guage from Harbor Freight Tools that has a fitting to screw on the schraeder valve. I could not get a tire guage to work. I tried and got soaked with fuel.

 

Screw it on when the truck is off. Make sure that it is fairly tight, or you will get wet with diesel. Ask how I know?

 

I believe to 0. They're both tire guages just one is a big dog.

 

I guess I'm not much more help for you then Jacob. I'm sure someone else who has used a stick gauge will pop in. Southern's way would sure work but that's cheating..

 

Thanks southern79. I went and got me one. Oughta have it done here pretty quick now.
That's cool Darin. No worries. I guess I'm gonna cheat too. I broke down and got the harbor freight rig too.

 

Truck OFF- Scew on tight!

 

I use a stick Gauge, Just a cheepie.
gotta hold it on there tight.

gotta make suer to clean it out too
i checked air in a few tires with it ASAP when I was done.
