Fuel cap o-ring size

aero3113

Does anyone know the correct size o-ring for a fuel cap. When I took my cap off last night to fuel up it split and fell into the water before I could catch it. I have some o-rings that look like I should be able to stretch over the threads but would like to get the correct size.

Post what boat you have. They may all be different....

Sorry, 2001 242. I think the caps for most years are the same.

Replaced mine last year.  Still in perfect shape this year.

Perko also makes replacement o rings. I don't have the model number at my current location, but I can get it for you when I get home. They usually stock them at West Marine.

Thanks Cableguy, I did order the ones that gslpro posted but others may want the number that you have.

I came home from work yesterday and the new o-rings were in my mail box. By feel you can tell they're a better quality then the ones you get in the hardware store.
