I stay on the OBS powerstroke side, but am working on my brothers superduty. How can I check his fuel pressure? Mine is on the side of the filter bowl, but I cant seem to find his. Now if it is low is there a way to shim the FPR like I did to mine? Thanks

 

Welcome! I can't recall how to check the pressure, but yes there is a way to shim the FPR on the SD it's just a tad different than the OBS approach. I'll see if I can dig up the info for you.

 

FPR shim- clicky

 

There is a port on the rear of the bowl that you can take out and insert a threaded fitting.

 

Thanks!! A little more involved than my truck but looks like a project for tomorrow.. Reps sent!

 

not hard at all...click on the pic then fallow the 2 red arrows, little late but maybe some help to ya..

 

Nice! Got ya for that one. Is there normally something in the upper port shown in that pic? (too lazy to go look)

 

a plug....the pic shows the ITP fitting in place..and thanks Chase..

 

Nope -- just a plug you take out to install the fitting for the hose to the gauge...

EDIT: I'm slow. LOL
