For example, tell me:
* What model of Cummins engine are you interested in? Cummins makes a variety of engines for different applications (trucks, generators, etc.). There are many different models, including the ISB, ISC, ISX, and others.
* What application is the engine used in? Knowing the vehicle or application will help narrow down the engine type.
Once I have more information, I can give you the specific engine specs for your 1999 Cummins.
