ZTS All Fuel Production Numbers

[molinegb]

Were there any production numbers of all fuel Z's? I know of 4 - 1939 and 1-1940 Z of which only 1 has the all fuel tank and manifold. When did production of all fuel end 1940?

I have a 38 ZTU with what I think is the all fuel tank, but not sure what the difference is in the manifold

I think the exhaust manifold or the "heat riser" on them had different settings ( hot or cold, might have had a medium setting also ) for different fuels, namely gasoline or distillate.

The all fuel has a dual compartment gas tank, a switching valve on sediment bowl and like Alan says a heat riser similar to a U and a larger manifold.The switching valve assembly is the same on a U or G with kerosene setup.(I need one of those valves)

My cousin has our grandfathers 1938 ZTU -it has the dual tank and adjustment on the manifold.
I had a 1937 JTU with the Waukesha engine. It also had the dual tank and adjustment on the manifold. I don't know about production years.

Mine does have the dual tanks and the 3 position shutoff. I haven't inspected the exhaust manifold yet but will soon when I take the engine apart to replace the gaskets before repainting it.
