umpqua, if you feel strongly about the fuel bowl O-ring, I suggest searching ebay, and look for a bulk price. Personally, I have never had an issue with that ring. As I recall, it is above the fuel level. The only way it could leak is if the fuel lever is too high. If the fuel level is too high you adjust it. If you do not tinker with it, nothing wears that I am aware of that would change the fuel level.
I simply pull the pull dipstick, and rub oil on the ring. That probably is not needed, but my mechanical training has been to never install a dry rubber or rubber type seal dry. Oil, transmission fluid, anti-seize, vasoline, or any oil based lubricant.
