Back at it with the FFM on the 93 again! got home from work this evening and popped the hood just to check on it and the oil leak from the oil pump drive. Found the cap seeping fuel on the FFM. the fender wasn't wet but the cap and housing was wet. got my filter wrench and cranked down on the cap almost to the point I felt like it was gonna break. ran the engine a few minutes and it's still seeping! changed out the o-ring I had made back to the square shaped seal it had, and cranked it on some more with the filter wrench, figured if I break the cap I still have the inline filter I can put back on.
still has a slow seepage. not like it was but slowly beads up around the edge of the cap! There is no doubt, this truck is getting a filter housing like I put on the firewall of the 95. I had wanted it back OEM with the heater, but if it's this much trouble to get it sealed, I can do without it.
