I want to prove its failed before I replace it.
Otherwise. A line from a reservoir to the inlet side of the carburetor should provide sufficient gas to start her up? Provided the gas was higher then the carb. Right?

One concern would be if the diaphragm is leaking it can pump fuel into the inside of the engine. So you want to keep a lookout for that.
