NOTE: Lower the reductant tank slowly. Failure to do so can cause damage to reductant system components.
NOTE: While lowering the reductant tank, make sure the reductant tank filler hose is positioned loosely between the frame rail and the body panel.
9. Lower the reductant tank enough to access the reductant tank pressure line and heater connector.

   All Vehicles 

NOTE: When disconnecting the reductant pressure line from the reductant pump assembly, gently press the reductant pressure line connector towards the pump assembly and hold. Then press the connector tabs and pull the connector straight off the pump assembly nipple. Failure to follow these instructions may cause damage to the reductant pump assembly and the reductant pressure line.
NOTE: Do not use any tools when disconnecting the reductant pressure line. The use of tools may cause a deformity in the clip components which may cause reductant leaks.
NOTE: Disconnect the reductant pressure line before disconnecting the reductant pressure line heater electrical connector.
NOTE: Inboard frame mounted reductant tank pressure line shown in illustration, outboard similar.
10. Disconnect the reductant pressure line from the reductant pump assembly.
    1. Gently press the reductant pressure line connector towards the reductant pump assembly and hold.
    2. Press the reductant pressure line connector tabs and pull the reductant pressure line connector straight off the reductant pump assembly nipple.

11. Disconnect the reductant pressure line heater electrical connector.
NOTE: There are different reductant pressure lines for different wheelbases. Note the position and routing of the reductant pressure line and retainers to aid installation. An incorrectly routed reductant pressure line could become damaged during normal operation.
12. Detach the reductant pressure line routing clips.
13. Slide the reductant pressure line heat shield back to access the reductant pressure connector on the reductant injector.
