• Optimal Compatibility: Specifically designed to integrate seamlessly with the Lang Tools TU-443 Deluxe Global Fuel Injection Pressure Test Set, ensuring a perfect fit and reliable operation.
• Clear, Dual-Scale Display: The 3-1/2 inch gauge face features easy-to-read markings in both PSI and bar, enhancing usability and reducing potential for reading errors.
• Enhanced Diagnostic Capability: Provides critical data needed to identify issues like weak fuel pumps, restricted fuel lines, faulty pressure regulators, or leaking injectors, contributing to more efficient repairs.
• Reliable Performance: Constructed to provide consistent and dependable pressure measurements, supporting effective vehicle maintenance and troubleshooting.

SPECIFICATIONS:

• Gauge Diameter: 3-1/2 inches
• Measurement Range: 0-100 PSI (Pounds Per Square Inch)
• Measurement Range: 0-7 bar
• Included: One Lang Tools Gauge for TU-443 Set (21003)

HOW TO USE:

1. Safety First: Ensure the engine is cool, the vehicle is on a level surface, and appropriate safety gear (gloves, eye protection) is worn. Relieve any residual fuel pressure in the system if necessary, following vehicle manufacturer guidelines.
2. Locate Test Port/Connection Point: Identify the fuel pressure test port on your vehicle’s fuel rail or line. This often looks like a Schrader valve, similar to a tire valve. If no test port is present, you may need to disconnect a fuel line and insert an appropriate adapter from the TU-443 set in-line.
3. Connect Gauge: Select the correct adapter from your TU-443 set that matches your vehicle’s fuel system. Attach the adapter to the vehicle’s fuel pressure test port or in-line connection point. Then, connect the hose from the Lang Tools TU-443 set to the adapter, and ensure the 21003 gauge is securely attached to the hose assembly.
4. Prime System (if needed): Turn the ignition key to the “ON” position (without starting the engine) for a few seconds to allow the fuel pump to prime the system and build pressure. Repeat a few times if necessary.
5. Read Pressure: Start the engine and allow it to idle. Observe the pressure reading on the Lang Tools 21003 gauge. Compare this reading to the vehicle manufacturer’s specifications for idle fuel pressure.
6. Perform Tests (as needed): Depending on your diagnostic procedure, you may need to observe pressure during acceleration, deceleration, or with the vacuum line disconnected from the fuel pressure regulator. Utilize the relief valve on the TU-443 set to safely bleed off pressure and fuel after testing.
7. Disconnect: Once testing is complete, carefully relieve all fuel pressure using the relief valve. Disconnect the gauge assembly and adapters, ensuring no fuel leaks.
