Which fuel delivery system do I have

[noserider]

The data suggest the 5.9 ISB went to a common rail fuel system in 2003. My coach is a 2002 so it's supposed to have the VP-44. How do I verify this for MY coach? Newb questions I know.

Your chassis manufacturer , should be able to give you an engine serial number , and you could call Cummins Care. 1-800-343-7357.

Or look for the VP-44 on your engine, note; the fuel supply tubes, pump to the side of the cylinder head , look like a spaghetti factory.
Common rail has a fuel distribution manifold ( rail ) on the top of the intake manifold and the tubes go from there to the injectors ,I don't have a picture of that system.
