1995 and '96 were the only ones made with gas 5.7 TBI engines from the factory. '96's could have the optional aux. fuel tank, very needed due to the very poor fuel economy with the gas engine. (The tank was available as an add-on kit, too.)
Only about 750 gas models were built in the two years out of about 11,800 total built from '92-'06.
I used to work for the Hummer dealer in Huntington Beach, CA.
