O-ring for Tohatsu outboard fuel line?

[troppo]

Went to plug the fuel line into my 18 hp 2011 model 2 stroke Tohatsu and the connector didn't want to go on properly. Then it started to leak fuel. Found that there is a little rubber 0-ring in there that's no good. That was the end of my plans to get the motor going today.

Has anyone replaced an o-ring like this before? Checking the 'net for spares and I can only find the whole end connector. Surely these rings should be available somewhere [Hopefully in Australia : )]. Any ideas?

Get an accurate caliper on the diameter of the ring material, and the diameter of the place the O ring is fitted

then contact NAK (or similar)

making sure tha the material of the oring is suitable for 2stroke mix.

Problem solved. Thank you Talbot, after checking the link you gave, I stopped hunting for an outboard spare part and searched for a local o-ring supplier. Went to Applied Industrial Tech (formerly SKF Bearing Supplies) and got a replacement.

Actually, since they come in packets of 50, I had to get the whole packet. Only cost $5.15 so no dramas.

When I got to my boat and looked carefully at the new o-rings, I noticed they were a tiny tiny bit thicker. Hmm. Inserted it into the fuel line connector and tried to slip the connector onto the motor but no go. Wriggled it and still no go. Somehow ended up damaging the o-ring so pulled it out and put another one in. Hehe, lucky I've got 50. This time I put a smear of grease from the throttle coupling, which was handy, onto it and 'click', it worked. Ran the motor, no leaks from the hose so I am happy. Wow, the o-ring is only a 10 cent part but without it I can't run my motor.

Manufacturers charging a lot of money for a 10cent replacement are a source of annoyance to me.

I used to own a tohatsu 3.5 2stroke outboard. That same engine was used by a lot of other manufacurers with a different cover and badge. It used to amuse me a lot to compare the different prices for the same item between the manufacturers.

O rings are an easy one, it is always cheaper to go to an o ring supplier. Bearings are another area where you can save a lot of money getting one from a bearing specialist.
