the critical oil seal for the diaphram shaft.
==============================================================================
This oil seal does 100% "Nothing", it is not even a seal, the arm from the
fuel pump moves up and down on the cam shaft to push gas through the upper
half of the pump on top of the diaphram gasket, the so called seal has a
slit in it, with this arm moving up and down through a cut/slit/opening, how
can it seal anything out, also what harm can oil in the bottom half of the
diaphram do to the gas, "NOTHING", remove the seal and see what happens,
nothing, it will continue to run with or without out, unless the diaphram
it's self fails then you have a problem. "FT"
