Cummins 5.9L/6.7L Injector Fuel Tubes
100% New OEM 5.9L Cummins Bosch Fuel Tubes. This is a stock replacement part, it will not provide any extra performance. It is recommended to replace your fuel tubes as you replace your injectors.
Fuel tubes supply injectors with high-pressure diesel fuel. Reusing old fuel tubes can cause leaks, resulting in contaminated fuel going into your injectors. This will cause early failure of your injectors.
