My buddys truck is leaking oil from right under the fuel filter on top of the motor. I Think its the hpop. Am I right? There are two hoses that go into it. One is leaking right up against where the hose threads in. Is there any write ups on how to fix it? How big of a challenge will this be? you can wiggle the hose but the nut where it screws on seems to be tight is this normal or will he have to buy new hoses? Are there o-rings on the ends of the hoses? Sorry for all the questions its just that I have not messed with the 7.3 to much. Im just trying to get as much info as possible before tearing it apart.
