I just cahnged my fuel filter for the first time since I have owned it (1yr 4k miles). There was no O-ring anywhere. I put the new one on the lip of the filter canister so the lid would seal against it when tightened. I guess this is correct? Thanks!

 

I can't confirm if the 04.5 is the same as my 06, but on mine, the o ring goes on the lid, not the canister itself.

 

I have owned a 04.5 and now an 06 and they are the same... the o-ring is installed on the lid, prior to screwing the lid into the body..

Guess I better take it back off and put it on the lid. Where does it goon the lid? Thanks!

 

Slide it over the threads until is sits on the lip of the lid.

 

It leaks like crazy if it isn't on right, don't ask how I know.

 

LOL! Thanks guys. That's why I am here so you can teach the slow guy how to do stuff. Wonder how it worked w/o one on it?

 

Look in the filter bowl when you open it back up. It can stick to the canister and fall in once the lid is off.

 

I cannot believe it would not have leaked if there was not one on there. I would contend that it IS there somewhere. It may have just fallen off from being stretched out.
Yes, roll it on to the lid, over the threads, and smear some diesel on it before you put it back on. Kind of like you do with an oil filter....

 

It was hardened onto the lid, I found it. I don't think it was ever changed before. I did the oil change ( nasty stuff for only 4500 miles) put a new cold air kit on, and installed my SuperChips programmer on tow/haul. The trailer is hooked up right now, so I will get to give it a good test drive during a 6 hour round trip. Thanks guys!
