Freightliner Fuel Tee Retainer Part No: 03-22305-001

Freightliner part 03-22305-001 is a fuel tee retainer used to secure plastic or metal fuel tees within the truck’s diesel fuel line assembly. Proper retention is essential to maintain fuel pressure, avoid air intrusion, and prevent external leakage. As fuel connectors experience vibration, thermal cycling, and age-related wear, the retainer may weaken or deform. This OEM-style replacement ensures the fuel tee sits firmly within the line assembly, preserving system integrity and supporting dependable engine performance. Recommended during fuel line service, tee replacement, or preventative maintenance.
