Fuel Filter Housing Questions

[TchTchr]

Hey all,

My secondary filter housing is letting air into the system. After cleaning up the top of the housing and changing the crush washer and o-ring several times, I've decided to swap the housing with a newer style housing. The hollow bolt is shorter with TWO o-rings and there was no crush washer on it. While trying to remove the old housing, I stripped one of the cap screws. Now the questions:

I'm going to try to use an easy-out to remove cap screw. If that doesn't work, what next? Is the housing mounted to part of the block? It is hard to tell without removing the cruise control. Obviously using a torch to heat up the cap screw is out of the question with all that fuel around.

The o-rings on the newer model I got are flattened. Are these o-rings supposed to have flat edges or are they just old and worn out? I looked for replacements on fastlane but didn't have any luck.

Thanks in advance,
Brad
