First Gen Cummins 12 Valve 7mm to 9mm Fuel Injector Adapter Sleeve

Pricing: $34.99


1989 to early 1991 non-intercooled trucks or trucks that have had the cylinder head replaced with a unit with 9mm injector bores will require these adapter sleeves for installation of BOSCH Prince of Darkness 50hp Injectors.

These adapter sleeves will not require the use of a copper sealing washer when installing with new injectors as these will act as the sealing washer when torqued to spec.
