I went to get a gasket, and Cummins said they were no longer servicing the old style pump. So I updated the whole thing. New pump, new lines, (required for the new pump) and the gear pump came already on it for $4800.00. $4800.00 to fix a fuel leak! WTF! I would say the oring or a gasket should fix it on the 2350, as you probably already have the new style 2 cyl. steel plunger pump.

If you got 600k miles out of a set of ceramic plungers.. you should have counted your lucky stars!. Even the newest steel/titanium plungers have to be replaced every 400k miles (8,000 hours) of use.
