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.<br>

hate to say this, but chuck the Walbro pump. This type of
pump is no longer on the market because the internal
components will not handle high alcohol content fuels. It’s
a pity, they were good pumps. In fact they were installed by
British Leyland on the Federal 1975 Austin Marina because
the single zenith carburetor manifold as used on the MGB
conflicted with the original mechanical fuel pump. <o:p></o:p></span></p>

<p class="MsoNormal">I have two Walbro Dupree pumps or
filters (made in Cass City Mi USA). Would these have come
off one of my mga s? Are they a pump? 12 volt or 6 volt.
Many thanks. <o:p></o:p></p>
