Cummins FAQ
Which Cummins do I have?
Check your VIN or the engine tag under the hood. The 12V ran 1989 to 1998, the 24V 1998.5 to 2002, the 5.9 common rail 2003 to 2007, and the 6.7 2007.5 on.
Do parts interchange between Cummins engines?
Some do, like certain suspension parts, but most engine and fuel system parts are specific to one generation. Shop by engine and year, or send us your VIN.
