You need to check with cummins if 3 cylinder pump rebuild kit available. Plunger and barrel assembly has different part numbers on 2250 and 2350. And you cannot mix them. Otherwise you will damage the pump. Oil and fuel will mix.
If not, you will have to put 2 cylinder pump with updated fuel lines.
I would recomend to buy old 2 cylinder pump and buy $500 internal parts( new barrel plunger and tappets) and rebuild it. It will be cheapier thsn $3000-4000 on new pump.
