Two hard fitment gates apply:
1/4 in DEF suction fitting. Freightliner 6-gallon hose-bead tanks with Cummins engines use two 18 in DuraWRX headers that look alike. This one has a 1/4 in DEF suction fitting and fits 2014-2015 trucks. The 2016-2017 version has a 5/16 in suction fitting, and we also stock it. Check the suction line fitting and the Freightliner number on your old header before ordering.
Hose-bead tank. This header fits a 6-gallon tank with a 90 mm hose-bead opening. It does not fit six-bolt or SAE-flange tanks. Later Freightliner 6-gallon tanks use a six-bolt header, which we also stock.
Other versions available: DuraWRX 2016-2017 hose-bead header with a 5/16 in suction fitting; DuraWRX six-bolt header for later 6-gallon Freightliner Cummins tanks.
Common interchanges: Freightliner 04-30774-001.
The DuraWRX ASPFL-2384 is a new analog DEF header with a 1/4 in suction fitting for 6-gallon, hose-bead tanks on 2014-2015 Freightliner Cummins ISB 6.7 / ISL trucks. It replaces Freightliner 04-30774-001. Confirm the suction fitting size and the number on your old header before ordering.
