GM TBI Fuel Pressure Tester - Actron Manufacturing

The Actron CP7817 GM TBI Fuel Pressure Tester is an essential diagnostic tool for professional technicians and mechanics working on General Motors Throttle Body Injection (TBI) systems. This specialized tester allows for accurate and safe fuel pressure diagnosis on vehicles not equipped with a factory-installed Schrader valve or fuel access test port, providing a reliable method to assess critical fuel system components without modification to the existing fuel lines.

Key Features

• Dedicated GM TBI Compatibility: Designed specifically for GM TBI systems that utilize M16 x 1.5 line fittings, providing a direct and secure connection.
• Comprehensive Diagnostic Capabilities: Effectively identifies issues such as weak fuel pumps, faulty fuel pressure regulators, compromised fuel line integrity (e.g., clogged filters), leaking injectors, and fuel pump check valve integrity via leak-down tests.
• Clear and Accurate Readings: Features a large, easy-to-read gauge with a 0-60 psi scale for precise fuel pressure measurements.
• Safe and Clean Operation: Includes a built-in pressure relief valve for controlled and safe depressurization of the fuel system after testing, minimizing fuel spills.
• Professional-Grade Construction: Built with durable solid brass fittings and a 36-inch flexible connection hose for lasting performance in a shop environment.
• Multi-Language Instructions: Comes with detailed instructions in English, Spanish, and French to assist a diverse range of users.

Applications

This fuel pressure tester is crucial for diagnosing a variety of common fuel system faults in GM TBI vehicles. Technicians can efficiently perform fuel pump pressure tests to confirm pump output, conduct leak-down tests to identify faulty check valves or leaking components, and evaluate the performance of the fuel pressure regulator. It is also invaluable for pinpointing issues related to restricted fuel lines or problematic injectors that can affect engine performance and drivability.
