I believe the o-ring for my factory fuel cap is original. Anyone know off-hand the appropriate size for a replacement?

Johnny -

Would you clarify. Are you referring to the O ring in the fuel fill installed into the gunnel cap?

The o-ring on the actual removable screw cap on the starboard gunnel.

My Outrage is about 100 miles from me right now so I cant actually measure the part. I'd like to have the o-ring in hand if possible before my next trip for quick replacement.

I suspect at least some of the moisture issue I had with my fuel several months ago may very well have been from rain intrusion into the fuel cap. The area is sort of recessed and holds water (dumb design) and the boat sat uncovered for several weeks in our summer rainy season during its re-power process.

My boat is in my driveway under it's winter tarp. I can get a look and snap some photos if this will help. I need to get a measurement of the bimini sliders for a Guardian owner so it's not a big deal.

[Edit- Johnny - I notice you have the original design with the fuel tank in the rear (1990-1991) that was changed to the under floor tank versions. I hope my f ill (no pun intended) is the same as yours.]

Becarefull to get the right thickness o-ring as it will interfear with the cap and cause it to cross thread. I can speak from experience on this as it happened to mine, '90 outrage 19'

Pulled the tarp and took two photos. They are the last two in my Outrage album

Without pulling the gasket out (mine might break) I measured 1 1/4 inches in diameter and the thickness is ~1/8 inch. It sits in a groove that is recessed at the base of the threads.
