Duramax 6.6L Billet Fuel Filter Adapter Head for 1R-0750 (2001-2016)

Fuel FiltersCE / ISO 9001

The FJ-1R-0750-AD20 is a black-anodized 6061-T6 billet aluminum refit adapter head for the 2001-2016 6.6L Duramax diesel. It mounts to the factory GM 12642623 fuel filter head and converts the filter interface to a 1″-14 UNS-2B spin-on thread, so the head accepts 1R-0750 pattern filters in place of the OEM ACDelco TP3018 element. The filter head and the filter element are not included.

No. The adapter ships with an upgraded mounting bolt, so it combines with the 12642623 head without removing the check ball and spring inside it.

GM specifies 15,000 miles for 2001-2010 Duramax trucks and 22,500 miles for 2011-2016 trucks on the OE filter. With a 1R-0750 pattern filter, follow that filter maker's interval and shorten it for biodiesel or dusty conditions.

Description

Product Overview

The FJ-1R-0750-AD20 is a black-anodized 6061-T6 billet aluminum refit adapter head for 2001-2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks with the 6.6L Duramax. It mounts to the factory GM 12642623 fuel filter head and converts the filter interface to a 1″-14 UNS-2B spin-on thread, so the head accepts a Caterpillar 1R-0750 pattern filter in place of the OEM ACDelco TP3018 element. The adapter is supplied on its own; the filter head and the filter element are not included.
