Cant find replacement o-ring for 06 sportster fuel cap?

[holdnon72]

The o ring that seals the chrome fuel cap is cracking. My dealer has no listing for just the o ring. You have to buy entire fuel cap assembly for 169.00

it has to be the same thickness or could cause evap leak...

thanks for for any suggestions

I took my 04 gas cap to ace and found a o ring that matched.

Try to get Viton or HSN70 (HNBR70). These will stand up to fuel exposure better than plain old nitrile.

Google an o-ring supplier in your area. Minimum charge is usually $5 or throw a handful of change into their charity jar.
