I would suggest a stop down to the cummins shop, by the airport. They have a very large shop, and I would imagine, they do this frequently. Ask for the Marine exec., and he was helpful to me yrs. ago with a few questions. I buy most of my cummins, parts there, but have an engine guy that works on them. It is off the main road on the back side of the airport, ? RT176 ? EXIT 15 OFF RT97
