In the documentation for the Cavalier, it says you should keep extra O'Rings for the nozzle connection. Where can you purchase these and exactly what do you ask for?

Re: O Rings
Even better, make it a habit to check for the presence of the o-ring after you disconnect the fill hose. Our family has had 3 CNG vehicles for 6 years and we've never lost or blown out an o-ring. On the Cav it's even less of a problem since you can run on gasoline until you get an o-ring.02 GX

Re: O Rings
Common auto parts store "O" rings will work just fine in this application. For longest life try to find ones made of either Buna-N (nitrile) or neoprene. These materials are compatabile with NG. After removing the old "O" ring, make sure the groove in the fill recepticle is clean, apply a little Vasoline or silicone grease to the new "O" ring and slip it in place. When your car was new, three replacement "O" rings were provided in the glove box with the owners manual. For once, GM was thinking ahead.

Re: O Rings
If it leaks after the fuel nozzle is disconnected, the exterior o-ring is not the problem. Leaking after the nozzle is disconnected can be wet fuel freezing, dirt ,or the check valve in the recepticle itself .
The exterior o-ring will come out with a very small screwdriver or ice pick. It is held by a small ridge in the fuel recepticle.
