Rw, thanks for the reply. TFE paste is what I used. I purchased my fittings, from a local hydraulic shop. Maybe I'll dismantle, the few I sealed with tape, and try again with the paste. I don't believe that I ever ran it, after fixing the few leaks with tape. Once I had success, at stopping the leaks, I kind of wanted,to leave well enough alone. I was aware of the tape issues, but frustration kicked in.?
