So I called R/R Mack in Akron. Tell them what I need, he says, "yup, should have some, how many do you need?"> I tell him two, and he puts them in will call. I stop over on way home and get them. Little plastic sandwich bag with two little round tapered seals. The guy drops it on the counters and waves me away(as he picks up a phone call). He was busy and didn't want to mess with charging me the .05/each ?? I thanked him graciously and walked out. I pulled the line apart again(still dry) and removed my brass ferrel and then poked the original rubber "seal" out of the brass nut. I then slipped the nut on the line and then the new o-ring. I tightened it down and started it up. Dry, perfect. The line is still kinda "loose" feeling, but no where like it was. I was expecting a bit larger seal, but if this works for now? What the hell, it didn't cost me anthing LOL!!! I threw the extra one in the sidebox of the bunk for a later date.
