I just changed the Racor fuel filter element on my 336 this weekend. When I unscrewed the lower metal housing that holds the filter, I noticed the brown coating on the edge that meets the rubber sea inside of the top assembly had chipped so I now have a part brown coating/part metal surface to seal against the rubber. I chipped the rest of the brown coating away and ran the sealing metal edge across some very fine sandpaper to smooth it out. Everything went back together with no leaks but I later starting thinking that maby the brown coating could have been there to make a better and smoother sealing surface against the rubber seal. Has anybody had this situation before? Please advise.
