[Zmagnette] Fuel pump

[Fletcher Millmore]

Common aftermarket pump. Those pumps were sold under many names, incl AC 
and Autopulse. They came in 6V, 12V and 24V, high and low pressure. Not 
ground sensitive, and I think there should be markings for voltage. 
Originally had brass bellows, later replaced by rubber bellows. Until 
very recently and maybe still, the rubber bellows were still available, 
and usually that is the only part you need. Since the bellows were 
produced long after the ethanol additions started, I imagine that later 
ones would resist ethanol; no other parts are sensitive. Service repair 
kits used to include bellows, points, gaskets, and you could get either 
of two springs - which determine the output pressure.
