International Harvester 966 converted to run on propane. 2 forklift sized propane tanks mounted on the sides, and acting as front weights (don't turn too fast). Contains 248L of Propane
Maximum speed of 36 km/h
Fully realistic fuel pump system with a globe valve to turn propane flow on and off. The globe valve is at the front. the propane passes from both tanks through a hose, to and from the front of the tractor, where the globe valve is located. When the globe valve is opened, propane flows into another series of pipes leading to the tractor's fuel pump.
The 3D model of the globe valve was comically small if sized to fit the pipes. 3 reducing fittings have been added (1" to 1/2", 1/2" to 1/4", 1/4" to 1/8") to give the glove valve a normal size, but also to connect propane pipes realistically.
