The DTech DT590017 Fuel Injector Connector Tube Set for 2003–2007 Dodge 5.9 L Cummins diesel trucks is a direct replacement for the factory injector connector tubes. Also referred to as supply tubes, high-pressure connectors, connecting tubes, or feed tubes, these parts are critical for feeding fuel to the injectors. It’s recommended to replace them whenever the injector is replaced to avoid leaks and performance issues. The spherical end of the connector, along with the injector’s inlet passage, forms a high-pressure seal; leaks here can lead to high injector return volume, hard starting, and other issues. This product is sold as a complete set of six tubes.
