Restore the integrity of your fuel system with the Dorman 904-129 Fuel Injection Line. Designed as a direct replacement for your 2001-2004 GM 6.6L Duramax LB7, this line is a crucial component for ensuring the longevity and proper function of your new fuel injectors. Over time, original factory lines can become compromised by corrosion and other debris, which not only causes leaks but can also introduce contaminants that can severely damage the delicate internals of a new injector. By installing a new Dorman fuel injection line, you can eliminate these risks, ensuring your vehicle's fuel injection system operates at peak performance and protecting your investment in new injectors.
