The DTech DT670005 Injector Connector Tube Set for your 2007.5-2013 Dodge 6.7L Cummins is a direct replacement for your factory Connector Tubes. Often known as supply tubes, high pressure connectors, connecting tubes, or feed tubes, these are responsible for feeding your injectors with fuel. It’s recommended that these are replaced any time you replace an injector to avoid leaks.
The spherical end of the connector, along with the injector body inlet passage form a high-pressure connection. Leaks at this connection can result in high injector return volume, hard starting, and other performance problems.
