I'm in the process of repairing the leaky pump and was wondering what used to keep the pumps from leaking through the shaft hole and what position was it in in relation to the two small washers?

Yes, there should be a rubber washer seal around the shaft where it meets the brass hex-cap; there ought to be a spring pushing the crankshaft up against the seal, which may sit between two ball bearings though I have not seen that on some of the earlier model pumps.
