I think that is untrue. The later M-series 2.5 and 5 ton military trucks had a multi-fuel Continental engine that couldburn various petroleum products, but the pump had different orifices depending on the viscosity of the fuel.
Jeeps, or any carbureted engine, can burn a gasoline-favored mixture of the above mentioned fuels, but certainly not diesel straight. Think about it, if you could simply burn diesel in a gas-burner, everyone would have done it years ago when diesel was much cheaper than gas. WW2 Jeeps had the same carburetor (Carter WO) and fuel pump as civilian Jeeps.
