The main problem is the the gasket is not holding. heres no way that gasket will mate perfectly with that flange.Its not perfectly round like it shjould be. I am going to buy a filter with thecap to. Maybe the cap has the gasket already on there in the right place. I should no better then to go aftermarket. Leaking all over my engine an makin a mess. Poor patent in my book .

150ford,
I've only changed mine twice and each time, I have placed the beveled Oring onto the filter cap first. I think this helps to maintain a more uniform shape (round). Of course, make sure that the "point" of the bevel is pointing toward the top of the cap. Try turning the cap more slowly, once it makes contact with the oring. You'll get some resistance, but I kept turning slowly until the lip of the cap contacted the top of the bowl.
Additionally, the instructions mention to coat the orings with fuel prior to applying. Not sure how this affects the sealing properties?
Hopefully, you are not experiencing leaks associated with the orings in the fuel drain lever? This also has become more apparent with the newer fuel and older orings.

Do like Tenn suggested, and rub a bit of diesel fuel on the o-ring that sits under the cap, so that the o-ring can slip a bit as you're tightening down the cap, and not bind up. Make sure you have the threads lined up properly on the cap.
Are you still stuck on this? If so, let us know exactly where you are and what the problem is.

Hey guys got the fuel filter on right this time. Started it up an it now it has a miss that wont straighten out. I am afraid an injector went south on me. Maybe a trip to the dealer to see whats wrong. Off course the dealer is an hour an half away from my home. So guys would it be safe to drive it to the dealaer missing like this or should I have it hauled. I dont want to ruin the engine. Maybe it will clear up I dont know. It seem to run good when it is warm but I let it sit awhile you start it up again it misses terrible. Any diesel techs out there your help would be appreciated. Man my truck was runing just fine before this. Im not liking this fuel to well.

Are you saying that the "miss" was not there prior to changing the fuel filter?
If it only started afterwards, there may be some air in the fuel rails. Did you cycle the fuel pump a couple times to re-fill the fuel bowl after replacing the cap? It may take some time to elliminate the air, if this is the cause.
You state it runs fine when at Normal Operating Temp. Then you say after sitting awhile and go to start, it sounds like a bad injector. If the engine is "cold" again when you re-start, it sounds like a possible glowplug system problem.
Assuming that "nothing" else changed while working on the filter.

Did you fool with your drain valve? Also you may have bumped something. Check your GPR wires and UVC harnesses and anything you can see you may have disturbed. That injector likely didn't just die while you were battling with the filter cap.

Nope the wires were not disturbed at all I just checked. Yes I cycled the fuel pump about three times. The truck started an rough for awhile but straightened out. But now after I shut it off awhile an then strted its pretty rough. I blame myself for this I should have changed my fuel filter before this cold weather hit. I imagine I screwed up an injector starving the engine for fuel like this. Yes the truck was running perfect before this fuel filter plugged. I am not to crazy about this fuel. I have had my tractors fuel filters both plug up in the last week an the temp was not that cold. I sure hate this but I dont know what am going to do next.I ahte to drive it like this.

Ill drive it down the road for a few miles an see what happens. This was truck was starving off fuel just before I put the fuel filter in. I sure hate that. I just wish I would have changed it before it went this far.Maybe its just air who noes. Lets hope.

Yeah, go drive the air out of that thing. Also, how old is your oil?
Newb, some folks fill up the filter bowl to near the top before capping it. Pretty much making sure there's fuel there instead of pushing air around. Just a method and not really called for via the manual but I do it that way.
