Genuine Bosch injector feed tubes for the 6.7 Cummins — the connecting tubes between your fuel rail and injectors. Do not take a chance on reusing old feed tubes with a brand new set of injectors. Contaminated or worn feed tubes are one of the most common causes of immediate injector failure after a fresh install, and contaminated fuel failure is not covered under warranty by any fueling manufacturer.

These are the same genuine Bosch feed tubes we recommend and ship with every injector set we sell. An inexpensive but critical component that protects your injector investment. Do not let a low-cost part ruin a high-cost project.
