The Common Rail High-Pressure System Tester is a specialized diagnostic tool designed for the comprehensive analysis of diesel engine high-pressure oil circuits. It allows technicians to monitor fuel rail pressure in real-time, evaluate the condition of the high-pressure pump, and identify leaks within the injection system. Whether you are troubleshooting starting difficulties, unstable idling, or engine power loss, this kit provides the critical data needed to pinpoint failures in the common rail system efficiently.




High-Precision Measurement: Equipped with professional-grade gauges and sensors to provide accurate pressure readings up to 200MPa+ (depending on the specific gauge model).
Comprehensive Compatibility: Includes various adapters and plugs compatible with major common rail brands such as Bosch, Denso, and Delphi.
Leak Detection: Effectively identifies internal and external leaks in high-pressure lines, fuel rails, and injectors.
Portable & Rugged: Housed in a heavy-duty, blow-molded carrying case for easy transport and protection in harsh workshop environments.
Time-Saving Diagnostics: Allows for "on-vehicle" testing, significantly reducing the time required for system teardown and inspection.
Safety First: Features high-pressure resistant hoses and secure connectors designed to handle extreme fuel system pressures safely.
