The Service Manual mentioned removing the O-RING when you change fuel filter. However when I remove the filter, I DID NOT see any o-ring. Where's this o-ring located? I looked really good and I could not find this thing. Anyone experienced this before? Thanks.

 

Look on the "lid" that you unscrewed from the filter housing...look just above the threads on the top of the "lid" and you'll see the o-ring. It's there to seal the lid to the filter housing.

Thanks for the info. When I took the lid off, I did not see an o-ring. Someone must have forgot to install one.

 

Maybe it stuck to the housing and didn't come off with the lid? I'd think lack of an o-ring would have caused problems. But you never know.

 

I think the o-ring is not really a requirement. The threads make a good seal.

 

The new filter should have come with a new o-ring. Bothe the CTD filter and the NAPA filter do.

 

Mine also had no O ring when i changed my filter,new one did so i installed it...
