Fix or prevent fuel leaks on your 2001–2005 6.6L LB7/LLY Duramax with this GM Genuine FICM Fuel Banjo Washer Kit (98340724). Designed for the fuel lines running to and from the Fuel Injection Control Module (FICM), this kit includes two complete sets (enough for one truck) of OEM-pressure steel banjo sealing washers.
Banjo washers must be replaced whenever the FICM lines are opened up—failure to do so can cause persistent leaks or return faults. Each washer is precision manufactured to seal under factory torque and heat cycles, maintaining fuel system integrity and performance. Perfect for injector replacement, FICM swaps, and return line maintenance on both Chevy Silverado and GMC Sierra HD LB7/LLY engines.
