when sitting idle i feel a vibration in the cab. its not a constant vibration its like it gets worse then goes away then starts again. i didn't know is that just how the 7.3 are or not. iv just owned one for a couple weeks now
mine did this and i fixed it.
ICP sensor had oil coming through replaced it and it got slightly better.
last week changed my FPR ( fuel pressure relief) and the slight miss is completely gone now.
$60 for FPR rebuild kit from riffraff or dieselorings
im sure mine had never been changed in its 225k mile life.
hope this helps.
no it wasnt cause ive used additive for last 25k miles every tank.
the spring was clean but the brass poppet was very worn out.
the instructions also say you have to push the bushing out last, mine just fell out with the brass poppet haha
ok gotcha. i have rebuilt the housing with new o-rings but not the regulator. i have been inching closer and closer to getting the riffraff frx, and am wondering if that will cure a worn out regulator....
question. i have seen vids with guys hooking up fp meter to somewhere on the back of the filter housing. i looked and didnt see a fitting. does anybody know how they are doing that?
EDIT: i should have researched this before i asked. i found plenty on the subject....
