Lang Tools Basic Diesel Fuel Pressure Test Kit (TU-32-2)

The Lang Tools Basic Diesel Fuel Pressure Test Kit (TU-32-2) is an essential diagnostic tool for professionals and enthusiasts working with diesel engines. This kit is specifically designed to accurately measure fuel pressure between the lift pump and the injection pump, a critical step in diagnosing various engine performance issues. Whether you’re dealing with hard starts, rough idling, power loss, or suspect fuel delivery problems, the TU-32-2 provides precise readings to help identify the root cause. Its universal compatibility with most diesel engines, from single-cylinder models to large V32 applications, makes it a versatile addition to any toolkit. The inclusion of multiple banjo bolt adapters ensures you can connect to a wide array of diesel fuel systems.KEY FEATURES AND BENEFITS: Accurate Fuel Pressure Measurement: The included 100 PSI gauge (M91 model) provides precise fuel pressure readings, helping to quickly identify if low fuel pressure is contributing to engine problems. Universal Diesel Compatibility: Equipped with five banjo bolt adapters ranging from M8 to M14, this kit connects to a broad spectrum of diesel engines, ensuring versatility across different makes and models. Safe Pressure Release: A built-in pressure relief valve allows for safe and controlled depressurization of the fuel system after testing, and also enables quick resetting of the gauge for repeated measurements. Clear Fuel Flow Monitoring: A 6-foot clear PVC tube is included, providing a visual aid to observe fuel flow and check for air bubbles or contaminants within the fuel line. Complete Kit for Convenience: Comes with all necessary components, including the gauge assembly, hose, adapters, and a repair kit, making it ready for immediate use and easy to maintain.SPECIFICATIONS: Gauge Range: 0-100 PSI Gauge Model: M91 Hose Length: 4 feet Clear PVC Tube Length: 6 feet Banjo Bolt Adapters Included: 5 adapters (ranging from M8 to M14) Included Components: M91/100 PSI gauge with boot assembly, 4-ft. hose, pressure relief valve, 5 banjo bolt adapters (M8 to M14), 6-ft. clear PVC tube, 1 repair kit.HOW TO USE: Safety First: Ensure the engine is off and cool. Relieve any existing fuel system pressure according to the vehicle’s service manual. Wear appropriate personal protective equipment, including eye protection. Locate Test Point: Identify the appropriate test point between the lift pump and the injection pump on your diesel engine. This is typically where a banjo bolt connects to a fuel line. Select Adapter: Choose the correct size banjo bolt adapter (M8 to M14) from the kit that matches the fuel line connection point. Connect Gauge: Install the selected banjo adapter and connect the 4-ft. hose from the gauge assembly to the adapter. Ensure all connections are secure and leak-free. Perform Test: Start the engine (if possible) or operate the lift pump to pressurize the system. Observe the fuel pressure reading on the 100 PSI gauge. Record Readings: Note down the pressure readings at idle, under load, or at specific engine RPMs as required for your diagnosis. Depressurize and Disconnect: Once testing is complete, use the pressure relief valve on the gauge assembly to safely release the fuel pressure. Carefully disconnect the hose and adapter, and reassemble the original fuel line connections.BENEFITS OF USING LANG TOOLS BASIC DIESEL FUEL PRESSURE TEST KIT (TU-32-2): Provides accurate data for effective troubleshooting of diesel engine fuel system issues.
