Subject: Cummins 855 fuel pump help


live in Spfd, farm located NW Macoupin county
hoping some 855 Cummins help can be found here. The seal on the throttle input shaft is leaking on my fuel pump, pictures attached. Is that an o-ring or lip seal and can it be fixed in the field or does the pump need to be removed?
