I just had (Ok a week ago last Saturday) a problem with fuel leaking from between the filter cover, gasket and housing. [img]/ubbthreads/images/graemlins/frown.gif[/img] I found (what I thought) the cover to be a little loose. So I tightened the cover, but it still leaked. [img]/ubbthreads/images/graemlins/mad.gif[/img] I took the cover off and checked the gasket and the sealing surfaces. Everything looked OK so I put it all back together and it leaked more. [img]/ubbthreads/images/graemlins/mad.gif[/img] To try and keep it short, on about the 6th try I got it to seal. [img]/ubbthreads/images/graemlins/smile.gif[/img] During the week I picked up a new filter and gasket from NAPA. Installed it and had no problems with sealing on the first try. [img]/ubbthreads/images/graemlins/smile.gif[/img] Now during this I noted that at times it can be very hard to remove the filter cover. I also noted that I had to be very careful on threading the cover on, to prevent cross threading. (As far as I can tell it never did start to cross thread, but I just don't trust the plastic fiber fuel cover.) I was hoping that may be someone produced a billet cover with a better seal, but have yet to locate one. (No I'm not solicitating for sales posts, just putting it out that I looked).
Now my questions are as follows
1.) Has anyone else had this problem?
2.) Do you think it was just a bad gasket?
3.) How likely is it to cross thread the cover?
4.) From others experience, is this just a fluke that is most likely to not happen again.
As always thanks to those the take the time to put forth their opinions, ideas and past experiences.
Maybe the rubber beveled gasket for the lid was installed upside down? It goes on one way only. I never put in on wrong but I'd imagine it would leak like a sun of a gun if it's on wrong. Just a thought. [img]/ubbthreads/images/graemlins/shrug.gif[/img]
Yeah, I've actually had to really study the instructions that come with the filter to make absolutely sure that I have the bevel going the right direction. So far, everything has been good with no leaks. (note to self...you probably just jinxed yourself [img]/ubbthreads/images/graemlins/shrug.gif[/img]).
I wonder why the lid seal has to be beveled? Seems like a round oring would seal tighter, with less chance of getting it wrong?

I had this problem in the fall and after creating quite a mess I finally got it solved. Upon very close inspection of the lid under a magnifying glass, I found a small hairline crack in the lid. After $53 from the dealer, I got a new one and have had no problem since.

Thanks for the responses.
For awhile I had quite a time and I was sure the Murphy had caught up with me. I could just see an engine fire if the diesel had caught (and I had quite a bit of it all over the place). I'm sure I didn't have it wrong, but who knows. I had it off so much, even I couldn't tell you. I even went as far as to fine an 'O'-ring that came close to try; no go with it. The 'O'-ring sprayed fuel out of all sides of the filter cover.
I'm thinking now that the 'O'-ring must have a small defect or something. I know that the replacement worked the first time. I am keeping a close eye on it for awhile
I did wonder it the cover/cap could have been part of the problem. That is why I was looking for a billet unit that may be used an 'O'-ring (I like 'O'-rings better). But it must not be much of a problem for someone to invest and produce. With a new OEM at $30 to $40 approx, it's most likely not work the cost.
