GM #3994340. However, it's long discontinued from GM.


Something I should mention: I DO NOT recommend these locking caps for "on-the-road" use. That's because they leak fuel as they do not have a cam lock feature. They are OK for use when the car is parked in an area where you fear someone might put something into the gas tank or take fuel out of the tank but that's about it. Also, they are pretty easily defeated by anyone "in-the-know".

Bob,

There is a NOS 3994340 cap currently on Ebay (not mine) for $49.95 "Buy-it-now" and free shipping.

I would be concerned with someone trying to pry the cap off and doing damage to the rear deck. This would be more costly than a few gallons of gas.

When I was building my house the thief pried open and ruined a $3000 patio door to get a $300 compressor.
