Unless you're a museum, you've got at least enough miles on your 7th and 8th Gen Fords to have made a trip to the moon, and possibly even back. Those fuel injectors have provided faithful service in the 1983-1992 Ford 6.9L and 7.3L's through 7 presidents, and chances are they're due for replacement. if you're either restoring, or just keeping "old faithful" running and in the family, Diesel Power Products are proud to provide you a 100% new, no core required replacement option for your IDI.
