5.9L Diesel Engines With Automatic Trans.
If equipped with a diesel powered engine and an automatic transmission, an electric vacuum pump and vacuum lines are used to supply vacuum to the speed control servo(cruse control). A vacuum reservoir is not used.
I would follow the lines from there back to the pump you may have a sopt that is worn through.
