If you don't get an answer here post over on boatdiesel.com. A lot of good/professional mechanics with a wealth of experience. Price doesn't sound crazy but not sure what is driving the need for an injection pump. May need to ask you mechanic to be more specific.

He may have noticed some fuel under it in a valley or something like that. I had an injector pump going out on my 41 with 3208 Cats. There was a small amount of fuel sitting under it, nothing more than a drip or two but it was starting to leak. It's best to catch things like that prior to big problems cropping up. If the pump starts leaking and looses some pressure it will effect the injectors as well. They require a certain amount of pressure to work correctly or they start destroying themselves internally.

Those costs seem high to me. I was quoted $900 for full rebuild for the injection pump for my cat 3208's with about $500 in labor. A new pump is about $3k from Cummins.

In what geo area are you located? $900 is shockingly low and so I wonder if we are apples to apples; after much research I determined that the pricing I received was normal here in S. Fl.

Also FWIW in my education on this subject I learned that I had old version injectors (apart from the pump issue), so instead of servicing those outdateds, I upgraded to the new injectors.

Engines are running A+ and sound even more awesome too.

Ask him to explain and if no good reason emerges, let it go. As to a fuel leak, I had fuel weeping from the injection pump of my Kubota generator. A few $8 orings and I’ve fixed it. The injection pump doesn’t need a rebuild unless you are having performance problems. Even then, there are many things to check first. If you get more info post back.
