CUMMINS 4935976, OEM injector line, 6.7L Ram, 2007.5-2018, Cummins common-rail diesel, fuel supply tube, injector fuel rail line, direct fit, high-pressure fuel tube, diesel performance upgrade

This is the genuine Cummins OEM injector fuel supply tube — Part # 4935976 — for the #6 cylinder on 2007.5-2018 6.7 L Ram/ISB common-rail engines. This high-pressure line delivers precisely metered fuel from the common-rail to the #6 injector, restoring factory-spec fuel delivery and system integrity after corrosion, cracking, or vibration-related fatigue. Because it is built to Cummins’ original material and pressure specifications, you get correct fitment, proper sealing, and uncompromised reliability when installed according to factory torque procedures. Use this tube to maintain OEM performance in your Ram 6.7L — especially after injector replacement or if you notice leaks or pressure loss.

Installation Tips

High-pressure injector lines like this are generally single-use due to crush-seal fittings. Don’t reuse old sealing surfaces. When installing, clean and inspect the fuel rail and injector seating surfaces, align carefully, torque to factory specs, and check for leaks on first start. If previous failure involved metal debris or contamination — flush the system and replace the fuel filter before installation.

FAQ 

WILL THIS FIT MY 2007.5-2018 6.7 L CUMMINS RAM?
Yes — this is the OE #6 injector line for 2007.5-2018 Ram 6.7 L ISB engines (verify by VIN/ESN).

WHAT CYLINDER IS THIS FOR?
Cylinder #6. Other cylinders use part numbers 4935981 (#1), 4935982 (#2/#3), 4935974 (#4/#5).

IS THIS A GENUINE CUMMINS PART?
Yes — OEM Cummins 4935976, manufactured to Cummins specs for high-pressure injector feed.

CAN I REUSE MY OLD HIGH-PRESSURE LINE?
Not recommended. High-pressure lines are single-use due to crush-seal interfaces. Always install a new line.

DO I NEED ANYTHING ELSE TO COMPLETE THE JOB?
Inspect and clean rail & injector seats, use new sealing washers, and check adjacent lines for corrosion or damage. Replace fuel filter if contamination occurred.
