🔌 Function

Transfers DEF through the dosing injector to pump circuit while maintaining dosing-system pressure and purity.

⚠️ Common Signs of Failure

• White crystalline deposits building up around the couplings or along the line
• DEF level dropping faster than consumption explains, with a wet patch under the run
• SCR or NOx fault codes and a power derate as dosing pressure fails to build
• Line swollen, cracked or kinked, or the outer sleeve split where it is clipped
• Slow or failed pressure build after a cold start, with the heated line not clearing

🛠️ Service Notes

• Renew the coupling seals when the line is disturbed and refit to the original clip positions, as a pinched DEF line upsets dosing pressure
• Flush urea deposits from the fittings with clean demineralised water only, never with fuel or solvent
• The 1500 mm and 4300 mm versions of this injector-to-pump line are separate part numbers, so measure the run before ordering
