I've had good luck with the AutoZone mechanical pump on my '78. It's
about $40, and is Italian made. It can be diassembled to clean or to
replace the diaphram. It comes with a gasket, but you need to reuse
the spacer block. I just asked the AutoZone guy if they carried one
for my car, and he sent over to their local warehouse to get it. I've
got a couple thousand miles on it with no trouble...The inlet/outlet
were oriented differently , requiring a slightly longer length of
intake hose (or you could take it apart and shift the case halves to
make it look like the original). I just used a longer hose and all
was well.
