'08 locking gas cap?

[Hmmm2]

I've been trying to find a locking gas cap for an '08 H2. No one seems to have one that fits. I didn't really want to buy the whole locking fuel door again. I had the locking fuel door on the H3 just as a precaution. Has anyone had any luck with locking gas caps? Do you think it's even necessary? Thanks for any advice!

For some reason, GM changed the fuel necks of the tanks from 07 up. I have not been able to find a locking cap either. I have the locking door on my truck just for a piece of mind. I am pretty certain there are tank baffles to prevent siphoning fuel out with a hose. On another note, I would like to have one for all those tree hugger Hummer haters around, I would not leave it unprotected!

No wonder I can't find a locking cap. I checked with the dealer and they said there's not much of a problem with people messing with the fuel tank. More of a problem in S. California are carjacked Escalades and H2's with Mexico so near.

Thats the dumbest excuse for not making a locking cap that I've ever heard.

The first thing I changed was the gas cap when I bought my 08. I picked it up at pep boys here in bay area, ca. Its made by Stant, cant recall the part # but its identical fit, when you plan to change it out make sure you dont cut the plastic tether, wedge out the plastic ring that fits on the outside of the cap, this fits perfect on the new Stant cap.

Hope this helps..

That's good to know, funny I called the dealership, and they still say there is no such thing!

The dealership will tell you that as there was never a locking cap released for the H2. The H3 has one as an export option only but not for the domestics. I am not overly familiar with the H2 fuel cap, but the standt cap, as long as it is the same thread should work just fine for your application. Standt makes a decent cap. And FWIW if you change it and start to see a check engine light, your first place to look would be the filler cap....

I was bidding on a locking fuel cap for my h2 on ebay, supposed to fit ALL years. From these posts it looks like the 2007 and 2008 might be left out. Should I be weary of purchasing this cap that supposedly fits all years?

Well, WikidPete said he had very good luck and a perfect fit with the Standt fuel cover from PepBoys. I didn't get to go over there yet. When I sopke to the parts mgr at my local Hummer dealer, he said a locking cap wasn't made for the '08. He said he has seen a couple of H2's come in with non-GM caps that didn't fit. He said they could be jimmied off quite easily by someone wanting to do damage. Do you have a PepBoys in your area? I'll try to check mine out tomorrow and keep WikidPete's positive experience in mind.

no... not at all... your only issue that you might have would be the check engine light may come on if there is an issue surrounding the ability of that cap to seal.... so don't throw your old cap away for a few months anyhow.... (wait till the warm seasons first)

Thanks! I'll call PepBoys in the a.m. AGAIN! I called them when I had first posted my question and they said they didn't have one for the '08. Better idea, I'll just drive out and talk to someone there. I'm glad you mentioned the plastic tether! I didn't know you could wedge it out. Thanks for your info.
