I have a class 3 fuel leak on my 2003 6.0 td, its on the front side of the secondary fuel filter. i was wandering if anyone had a exploded view of this and part numbers for new o-rings. thank you

 

not sure of the number but if you take off the oring and inspect first of all.if you go to an ih dealer they should be able to give you one. good idea to closely check the cover if someone overtightened they have been known to crack as well
