This pump is commonly used on the lower HP versions of the B series Cummins. I have used these for years with no trouble and also rebuilt a few. A few minor issues are, first, the minor and major rebuild kits do not include the engine oil seal. NAPA part number 6904 will work. Automotive oil seals such as this one use a thin steel tension spring that will rust away after a few years storage in a marine environment. I noticed my spare seal was ruined while inspecting the spare engine parts. Consider packing any spare oil seals with grease and storing in a Zip-Lock bag to prevent failure. Of less concern are the two size 6202 ball bearings also used to rebuild the pump. These are available from McMaster-Carr as part number 6153K56, but regular steel bearings are fine if they are also packed in grease.
