2007 5.4....Recently coming off a timing job, truck started by the way and ran smooth for a while....
The problem is as i was wrapping up all the electrical connections under the hood, i accidentally disconnected the Fuel Injection Pressure vacuum hose......the truck ran ok for a little while then it kept quiting on me(fuel starvation?)...actually posted on a FaceBook group, and most pointed at the Fuel Pump Relay Module....it didnt dawn on me till AFTERwards that its probably vacuum hose related, it clicked in my head, i do remember struggling to find where it really goes, got distracted and started working on something else....was havig a frustrating day........i took as good of a pic as i could take, if like to know where the hose goes


Second possible vacuum related issue is the brake booster line, particularly the steel pipe line.... when my truck is on, the brake pedal remains very hard, and difficult to brake, its not building pressure...... you can see line outlined in red down to the circle where it looks like a hose goes...

p.s. i tried researching on my own, but got diagrams for other engines of different makes and models.... i do know a local mechanic that is good with Fords, but he isnt cheap.....i did manage to do most of the timing/phaser job myself, and would like to be able to



connect or fix the vacuum hose issue i have going on
