how do i test the fuel presure on 03-7.3
 

well looking to do a fuel presure check on my 7.3 diesel can anyone let me know or just tell me were i check the fuel presure at??? just wanna make sure i am getting the right reading... in the right spot

on the side of your fuel bowl there is a shreader valve. it looks like a tire valve stem. with the truck running put a tire gauge on it. fuel will spray out of it. so be cautious.

thank u i will try it in the mornning

:argh:???????????? anyone help ??

here is how i did it on my dodge if it helps How to check fuel pressure for Under $20

well the dodges are definatly different than the 7.3s but thank u for the tip....all i need to know is do i check the presure before the filter or do i check the presure in the head were the fuel runs through ???

the first thing is to make sure are getting pressure from the filter before u check any farther. Lay under your truck and chase the line from the tank to the filter and see where u can put in a tee and a guage
