Check your fuel cap gaskets

Mine looked like yours. I just replaced them last year - they were 12 years old.

Good reminder to check them.

Yes, O'ring, not gasket. :D. Fuel/solvent resistant
 
What is the size/spec of O-ring to get for the gas caps?

Take the old one to your local Hydraulic shop.👍 :thup :thup
 
This is what I got, second season and work good, no leak.

126 Buna-N O-Ring, 50A Durometer, Round, Black, 1-3/8" ID, 1-9/16" OD, 3/32" Width (Pack of 30)

I think the "buna-n" is solvent resistant, O-ring made of other material might not last as long if exposed to fuel or other solvent.
 
C-Wolfe,

I sure am glad you posted the specs of those o-rings. I don't know how I would ever figure it out otherwise. I noted there are a zillion o-rings on Amazon. Only the 30 pack is available. I paid less the $10 for them.

Here's what I found on this "buna-n" material:

Buna-N (NBR) o-rings are recommended for
silicone greases and oils,
water,
petroleum oils
& fuels.

Buna is not recommended for
ketones
halogenated hydrocarbons
auto, & aircraft glycol-based brake fluids
strong acids
& not resistant to sunlight, ozone or weathering.

Benefits of Buna (Nitrile)
good wear resistance,
good compression set resistance,
good short-term resilience, and
good permeation resistance

Common Applications for Buna
hydraulic oils and fuels
extreme service-life
pneumatic
& vacuum
