If it wasn't leaking, I would reinstall it the same as the one that came off.

I just looked in my green book, and there is no picture of the filter. It just says to lube the filter seal. They may not have been that way originally. I would be willing to be the inner o-ring was added later to help keep the clean fuel from mixing with unfiltered. I'm sure it can't hurt.

well, done.
the new inner o ring didnt fit tight to the stud so I had to position it carfefully on the filter and raise it up and thread. took a few tries but I got it. Doesnt seem to be leaking any. THere is leaking fuel but I think that is comming from my pump above. Seal or maybe just where one of the injector lines comes to the pump. Any one know what size that injector line nut is? I am going to loosen and tighten the ones that look wet.
