Two hard fitment gates apply:
10-gallon tank only. Freightliner-built Cummins chassis also use 11.5-gallon, 13-gallon and 6-gallon DEF tanks, and those take different headers, which we also stock. This 14.5 in header is sized for the 10-gallon tank. Check the Freightliner number on your old header or the tank label, or measure the old header, before ordering.
SAE J2587 flange tank. This header bolts to a tank with an SAE J2587 flange. It does not fit hose-bead, six-bolt or bore-seal tanks. Headers for six-bolt and hose-bead Freightliner tanks are available separately, and we also stock them.
Other versions available: DuraWRX headers for 11.5-gallon, 13-gallon and 6-gallon Freightliner-built Cummins DEF tanks.
Common interchanges: Freightliner 04-37614-000 / 04-36003-000 / 04-35162-000 / 04-34396-000 / 04-31923-000.
The DuraWRX ASPFL-2339 is a new DEF header for 10-gallon, SAE-flange tanks on Freightliner-built chassis with Cummins B6.7 / ISB 6.7, ISL and L9 engines. It replaces Freightliner 04-37614-000. Confirm the tank size and the number on your old header before ordering.
