      Thank you for the very detailed guidance. A follow-up question – when I look at the parts diagram, it looks like the teensy o-ring fits on the outside of the housing (possibly just behind the conical end). But apparently not. The fuel valve pin assembly has two o-rings (the teensy one and one of the larger) and the air valve pin assembly has just the larger o-ring. Am I correct? I just ordered two core plugs so I can’t do the job until they come in. As I stated in my opening post, the fit between my new fuel line kit (hose /bulb/end connectors) is quite sloppy (as in loose) where it connects to the tank. Replacing the o-rings and core plugs will not change the loose fit (I don’t believe). The loose fit is OK? as long as it doesn’t leak air or gas?

        The o-ring are accessed exactly as the diagram shows. Removing the core plug and pin & spring allows you to get the larger o-ring. Once the pin is out, you can remove the little brass washer and the little o-ring which is behind the brass washer.

        I don’t expect a tight fit-up of the hose connector. Unless it is exceedingly loose, it is normal. If it is exceedingly loose, it is a worn-out or incorrect hose connector, not the tank fitting.

          Thanks. I wish somebody offered a tank fitting rebuilding kit (all three o-rings plus the core plugs), as all parts are necessary to do the job.

            Frankr – I’m doing the o-ring job on the fuel tank fitting/connector (thank you for the step by step directions) and I have a coupe questions. The small brass washer and teensy o-ring – I’m assuming they come out at their end (not pushed out thru the core plug end? Also, with the new o-ring in, the spring (and pin) don’t seem to want to go all the way in. The spring appears to be getting hung up on the o-ring and won’t reach it’s destination. I don’t want to try to force it. Ideas?

              How can the spring get hung up on the o-ring? The spring doesn’t get anywhere near the o-ring. Put it together per the diagram.

                You are right – thinking about about it overnight, I realized what I was doing wrong (even as my ears are still ringing from your response, but I deserved it!).
