The height differential between the supply module and dosing module can not exceed one meter. The supply module is
integrated into the DEF tank assembly, separation of the module from the tank is not allowed.
When relocating the components the maximum pressure DEF hose length, from Supply module to Dosing Module, is 3
meters (118”).

fIGurE 4-7: RH Under Cab Exhaust with Clear Back of Cab Tank.
The installation and design of the Clear Back of Cab (CBOC) tank is highly integrated into the chassis and cooling system.
Kenworth does not allow relocation of this tank, only relocation of the supply module.
The height differential between the supply module and dosing module can not exceed one meter. The CBOC tank does
not have an integrated supply module. The standard KW installation is a supply module located inside of the frame rail.
When relocating either the supply module or the tank, the maximum height differential between the supply module and the
bottom of the tank is one meter. The maximum line length is 2 meters between supply module and DEF tank sending unit.
When relocating the components the maximum pressure DEF hose length, from Supply module to Dosing Module, is 3
meters (118”).
DEF Pressure hose must include a “trap” in the routing if Dosing Module is below the highest point of the Supply Module
(See Figure 4-9 on page 4-9).
