Locking Gas Cap for '04

[GPmax]

Does anyone know where I can get a locking gas cap for my '04 GP? Will a cap designed for an '02 or '03 GP work on the '04 ?

FYI in case anyone cares or needs one for their 04 GP:

I found the right cap. I called a few auto parts stores. None of them list a locking cap for 04 GP's. I even called the dealer and they do not show it in their catalog.

I found rockauto.com and they list a locking cap here:

I ordered the part, it's on my car and working just fine. BTW it's the same exact cap that was on my 02 Blazer. So this cap must be fairly common.

Just looking into getting a locking gas cap. With the one you pointed to in the link, have you had any emission lights come on? I heard the reason, from the dealership, that they didn't have a locking gas cap was because these "new" gas caps allow a certain amount of vapor to breathe out.

Thanks!

I have been using this locking gas cap pretty much since I had the car and no lights or trouble.

Hope this helps...
