If you were really smart you would have ditched your pump and installed
the Aeon pump instead. More expensive than the normal dry pump but the
next best thing to a wet pump.

Just a warning for those who might consider purchasing Rapco dry vacuum
pumps. Make sure that your engine does not leak oil. If there is any
chance of an oil drip onto the Rapco vacuum pump it may eventually stop
working. The connecting shaft is vented to air. But if some oil drops
on the shaft it may get sucked into the pump and after the oil dries it
may seize the pump. I puchased a 216CW new pump from Spruce and after
20 hours of use it does not work. After returning it to Rapco they said
it was "oil contamination" and not eligible for warranty service, but
offered to replace it at a discount. They really ought to have a better
seal there to prevent the problem.
