Fuel Injector Return Line Adaptor - Kent-Moore

The Kent-Moore CH-50375 Fuel Injector Return Line Adaptor is an essential diagnostic hose assembly designed for accurate fuel return pressure testing on late-model diesel systems. This specialized tool provides a direct, service-grade connection within the fuel return circuit, enabling technicians to integrate a pressure gauge without altering factory lines. It is crucial for precise troubleshooting of fuel system performance and drivability issues, especially on vehicles equipped with piezo-activated injectors.

Key Features

• Direct-Fit Integration: Replaces the factory return line fitting, providing a secure, leak-free connection for real-time fuel return pressure measurement.
• Piezo Injector Compatibility: Engineered to support diagnostic procedures on fuel systems utilizing piezo-activated injectors, common in newer diesel engines.
• Accurate Diagnostic Capability: Facilitates efficient identification of issues such as restricted return flow, faulty return pressure regulators, or injector-related problems.
• Broad Gauge Adaptability: Includes an adapter to convert the 14mm British pipe thread to a standard 1/8" NPT port, ensuring compatibility with common shop pressure gauges.
• Professional-Grade Construction: Manufactured by Kent-Moore, ensuring a robust design suitable for repetitive use in demanding shop environments.

Applications

This adaptor is engineered for diagnosing 6.6L Duramax diesel fuel systems, specifically on 2010 G Van and 2011 C/K Truck platforms. It is commonly utilized on GMC Sierra and Chevrolet Silverado models equipped with piezo-activated 6.6L Duramax diesel engines. Technicians will find this tool invaluable for confirming correct return line pressure when troubleshooting hard-start, no-start, rough running, or loss-of-power complaints related to fuel delivery, helping to ensure return side pressure is within the required 58-160 PSI range for proper injector function.
