O.S. Max FS-70 Ultimate question

Does it pressurize the tank? If so what is the max pressure?

Thanks

The fuel system of the O.S. FS-70 Ultimate pressurizes the fuel tank. We're sorry, but a pressure specification is not included with any of the engine's data.

Can I convert my FS-70 Ultimate to run without the pump?

The FS-70 Ultimate is not easily converted to run without the pump and regulating system. You'd have to change out at least the carburetor and rear cover, and likely the intake manifold, too. We've not tried this, so we can't be sure.
