International Harvester 966 Propane

International Harvester 966 converted to run on propane. 2  Forklift size propane tanks mounted on the sides. acting as front weights (just don't turn too fast). hold 248L of propane. 

36KPH max speed

Fully realistic fuel pump system with a globe valve to turn the propane flow on and off. Globe valve is at the front. propane goes from both tanks up a pipe, forward, and to the front of the tractor where the globe valve is. when the globe valve is open, the propane flows up into another series of pipes going into the fuel pump on the tractor. 
The 3d model for the globe valve was comically small if it was sized to fit the pipes. 3 Reduction fittings were added (1" to 1/2", 1/2" to 1/4", 1/4" to 1/8") to make the glove valve a normal size, but also make the propane pipes connect realistically.
