KEY FEATURES AND BENEFITS:

• Designed for GM 6.6L Duramax Engines: Specifically engineered for all model years of the GM 6.6L Duramax diesel engine, ensuring compatibility and accurate readings.
• Comprehensive Fuel System Testing: Allows for both positive fuel pressure and vacuum testing, providing a complete diagnostic overview of the fuel delivery system.
• Clear and Accurate Gauge: Features a 3-1/2 inch gauge that provides precise readings from 30 inHg (vacuum) to 15 PSI (pressure), helping to identify subtle issues.
• Extended Reach Hose: Equipped with a 6-foot hose, offering ample length to connect to the fuel system test port while allowing the user to view the gauge comfortably.
• Effortless Connection: Includes a quick coupler for fast, secure, and leak-free attachment to the vehicle’s fuel system test port, streamlining the diagnostic process.

SPECIFICATIONS:

• Gauge Size: 3-1/2 inches
• Measurement Range: 30 inHg (vacuum) to 15 PSI (pressure)
• Hose Length: 6 feet
• Product Dimensions: 12″ X 7.65″ X 2″
• Included in Kit: Gauge assembly with 6-foot hose and quick coupler.

HOW TO USE:

1. Prepare the Vehicle: Ensure the engine is cool and safely shut off. Locate the fuel system test port on your GM 6.6L Duramax engine (typically near the fuel filter or fuel pump).
2. Connect the Kit: Attach the quick coupler on the Lang Tools TU-32-6 hose to the vehicle’s fuel system test port. Ensure it clicks securely into place.
3. Start Engine (for pressure testing): For fuel pressure tests, start the engine and allow it to idle. Observe the gauge reading. Compare this reading to the manufacturer’s specifications for your specific Duramax model.
4. Perform Vacuum Test (if applicable): To test for vacuum, some procedures might require the engine to be off or specific actions to be taken (consult your vehicle’s service manual for detailed vacuum testing procedures). The gauge will show negative readings (inHg) if vacuum is present.
5. Interpret Readings: Analyze the pressure and/or vacuum readings on the gauge. Readings outside the manufacturer’s recommended range indicate a potential issue within the fuel system, such as a clogged filter, a faulty fuel pump, or air in the lines.
6. Disconnect Safely: Once testing is complete, carefully release any residual pressure in the system (if applicable, consult vehicle manual). Then, press the quick coupler release and disconnect the kit from the test port.
