Most needed parts are available from your local O-ring or bearing supply
house. But first, you must determine for sure exactly where the leak
is/are. To do this, spray with gunk all around, under side too and hose
off. Idle or drive a bit and look/feel for oil. The shaft seal is an
unlikely leak source, inasmuch as it is under slightly negative pressure,
the reservoir level being a few inches lower. Much more likely, one of the
cylinder head O-rings. If you don't have a drag link socket, just use a
chisel to tap the head loose and use the largest flat blade that you have to
unscrew. If a lower one you may have to remove the pump, but don't
disconnect the hoses, if possible.
If you can find the leak, I have the o-ring p/ns.
