1/4 in DEF suction fitting. Freightliner 6-gallon hose-bead tanks with Detroit engines use two 18 in DuraWRX headers that look alike. This one has a 1/4 in DEF suction fitting and fits 2014-2020 trucks. The 2016-2024 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.
