ISX15 CM2250 fuel pump timeframe?

yes you can rebuild the 3 cylinder pump, but i would advise against it. most of the pump failures i see are with the old 3 cylinder pumps updated or not. just update to the 2 cylinder pump and put the new guts in it. the whole rebuild kit is about 800 Canadian to redo the guts and takes about an hour labor.

dont leave 3 cylinder pumps on engines they are bombs!
