          The factory part is 0344037 1963 Johnson 3 hp and such. $5 ea. It is flat rubber with a hole in it like if you cut 1/4 inch off a fuel line. I have been using a fat O ring that can handle the fuel. Someone in the club listed the o ring part number 4 or 5 years ago. I bought 50 of them, but ran out. super cheap.

                  For off the wall applications or hard to find Orings, this store will normally have what you need and shipping is sometimes better.

                      Same here Pappy. I checked it out and looks to be another good source, so I bookmarked it.
