Keep your fuel delivery system performing at peak efficiency with the OEM Cummins Fuel Pressure Sensor #4921519. Designed for the 6.7L ISB / QSB engines that comply with EPA‑13 emissions (commonly used in Freightliner and other medium/heavy duty trucks), this sensor monitors the fuel pressure accurately and sends critical data to the engine’s control module. Incorrect or failing sensors can lead to performance issues, higher emissions, fuel inefficiency, or even engine damage — this sensor ensures you get real‑time, reliable feedback so your engine runs clean, smooth, and within spec.
- Matches original factory spec—ensures compatibility and maintains warranty/standards
- Designed for ISB and QSB 6.7L EPA13 engines, used in Freightliner models and similar trucks.
- Helps ECM regulate fuel delivery properly — supports fuel efficiency, power, and throttle response. Also important for emission control.
- Available direct from Cummins or high‑quality aftermarket makers (PAI HDKits, Dorman, Automann, etc.) that meet or exceed original specs.
