There is a settiment bowl under the large tank. There should be a twist valve on top of that to turn fuel on and off for that tank. There should be a line running from the top of sediment bowl to the carburator. There should also be a fuel line running from the top of sediment bowl that loops around to the additional gas tank under the hood. It may have a sediment bowl under the little tank and a twist valve to turn on and off the fuel in the little tank. My little tank has a sediment bowl too. Not sure if they were all like that. The dual fuel burning H's were either gas and kerosene or gas and distillate. The gas went in the smaller tank under the hood. The kero or distillate went in the larger tank. The suffix letters in serial number indicate what fuel it will burn. X1 means gas. Not sure what indicates distillate of kero. These tractors had to be started on gas to pre-heat engine and bring it up to normal operating temperature. A cold engine would not run on the distillate or kero. Then you would change the manifold adjustment to the heat position, turn the gas off and turn on the fuel valve to the other tank. Tractor would have to be switched back to gas burning for shut down or the tractor would not start once engine cooled down. These tractors were equiped with radiator shutters to aid in warming tractor up and keeping it running warm. Since the engines were designed to start and shut down on gas it will not hurt the engine to run all the time on gas. You can even put the gas in big tank if using gas all the time. Use the little tank for a reserve if it is functional. Make sure the manifold is in the non-heating setting, and the shutters are open when burning gas. Kerosene and distillate fuel were cheaper to burn in the 40's, but it is no longer feasable to be burning these fuels today. Kerosene is likely higher than gas, and I don't think distillate is even available any more. If you have and want to keep the dual fuel burning equipment functional, that's O.K. but you would be better advised to just burn gas. Most of the duel fuel burners have just been burning gas now for decades. Many of the duel fuel burning tractors no longer have the nescisary equipment on them to burn the cheaper fuels anymore. Most of the manifolds (if ever replaced) now have the gas burning manifold. The radiator shutters were notorious for not functioning after a period of time and most were completely removed from radiator. The larger tanks were generally used for the gas and the smaller tank generally went tottally un-used for years. You know what that will do to a tank. The gas burning carb had slightly different jets in it. If carburator on duel fuel burners were ever rebuilt over the years, it likely has the gas burning jets in it now. The duel fuel burners were not an all fuel tractor. They were designed for either kero or distillate. Your off fuels today such as diesal or propane are likely not going to burn very good. Bottom line is, the extra duel fuel burning characteristics are neat features to have, especially if restoring to factory origin, but just stick with burning gas.
