Simple repair just escalated into a major problem I believe. I was trying to replace the o-rings around the stop lever. After getting to the o-ring on the shaft I proceeded to loosen the 17mm nut that holds the shaft in and a piece of the threaded injection pump housing broke off. Now the beginning threads on one side are gone. Do I have any options other than replacing the whole pump.
