Review on Stant 10596 Locking Fuel Cap by Ron Thomas

Will primarily fit 1994-2001 AM General Hummers and 2002-2006 Hummer H1 (name change was due to the introduction of the H2 in 2003). Revain listed this as incompatible with original Hummers, but it works. Not sure about the 1992-1993 AM General Hummer as they used a different gas cap. I lost my last locking gas cap and left it on my rear bumper when I filled up and drove away. I now make sure my key stays attached to the gas cap when removed so I can't start my truck without the gas cap being pushed in. my truck to try to tamper with my fuel. Easy to use and get the hang of it. Slight learning curve, but not bad at all.
