Tohatsu 18HP outboard?

[mestrezat]

Not sure if this is the right place to post this but what the heck.
I've got an 18HP Tohatsu outboard for my dinghy. The female fuel line connector has developed a bad O ring where it slides over the male fitting on the motor. I'm trying to find out the size of that O ring so I can get a replacement. Cheaper than a new fitting. I've taken out the ring and reversed it but still no real success.
Any one know the size?

By the way, the part number is 3GF-70250-0 if that helps.

Not familiar with your neck of the woods, but in most urban areas around the world there will be a bearing and seal type vendor. If you can find one, take the o-ring to them for sizing, and hopefully, replacement!
