Frame fuel filter seating?

I changed all the fuel filters and oil today the waterseperator filter(frame) didnt seat flush. The o-ring is not visiable but there is a 1/16th gap between the filtercap and housing i work on my big trucks but all their filters are metal canister or spin-ons. I torqued to 20ft/p and have no leaks but am scared of the plastic cap breaking if i tighen any more. If any one has a clue it would be great oh ya i said every cuss-word and almost ripped my thumb off some one should be tied to a tree and for running every-thing in front of a filter.
Thanks

Did you put any diesel on the O ring before screwing in the cap? I find that makes it a lot easier to seat in. Honestly never had a problem with mine, maybe you want to recheck that the filter is seated properly?

Was the filter the new one with the o-ring on the base? If so, I found that I needed to push the filter into the housing, then wiggle it a little bit while pushing. Doing that made it pop in an additional 1/4 inch, approximately. Then I put the cap on and tightened it until the lip met the housing.

No it was the old style. I took it off this mourning and made sure everything was were it needed to be. I removed the transfer case skid plate. That made it a lot easyer to get some room to work. Managed to get it flush with the housing but it is more than 20ft/p torque.No leakes. I also added a little grease to the treads and o-ring.

Exactly! fuel will make the 0-ring swell and harder to turn.

Thanks
I truely believe the 1st step in changing this filter should be.....

1) Take a 5 gallon bucket of diesel fuel and dunk your arms up to the shoulders.
2) sprinkle remaining fuel liberally accross upper body.....


I was yelling profanities accross the neighborhood..... good thing I live in a very rural neighborhood!!
