Genuine Mercedes 906 470 22 64 DEF Injector Feed Line Emission Reduction System

The Genuine Mercedes-Benz 906 470 22 64 Feed Line is an OEM diesel exhaust fluid (DEF) injector feed line designed for the emission reduction system. This line is responsible for transporting diesel exhaust fluid from the DEF tank to the injector nozzle in the exhaust aftertreatment system, enabling the selective catalytic reduction (SCR) system to properly neutralize nitrogen oxide (NOx) emissions.

Key Features:

• Genuine OEM Mercedes-Benz part — not aftermarket
• Direct-fit replacement for a precise, leak-free installation
• Engineered specifically for the Mercedes-Benz emission reduction (SCR/DEF) system
• Manufactured to Mercedes-Benz factory specifications and tolerances
• Also referenced as a Fuel Line / DEF Injector Feed Line
• California Proposition 65 compliant — WARNING: Cancer and reproductive harm

Replacing a worn or damaged DEF feed line restores proper fluid delivery to the SCR injector, helping maintain emissions compliance and prevent diagnostic trouble codes related to the DEF/SCR system. This genuine OEM component ensures the same fit, form, and function as the original factory-installed part.
