Replacement stepper motor to mount on the passenger side of the DS4 injection pump. Compatible with all 1994 and later 6.5L diesels with the DS4 electronic injection pump.  Simply remove the 2 screws (security bits may be required), remove & replace, to restore operation of a failed unit.  

Replacing this item will NOT resolve issues with a stuck advance piston.  These small electronic items are non-returnable, so ensure it is what you need before ordering.
