2006 H1 Hummer Main Tank Conversion
This is a 2006 H1 with the 6.6 Duramax engine and dual fuel tanks. We converted the rear tank into be a veggie tank with a hot fox. Next we added a 2 micron externally heated 6120 fuel filter, a Raptor adjustable fuel pump, and GV-10 valves under the hood. The whole system is controlled by an automated system that switches to veggie only when the coolant and veggie are both hot enough. If the operator accidentally turns the ignition off while burning veggie, the controller keeps the vehicle running for long enough to purge back to diesel and then automatically turns off the engine.
