Universal Fuel Pressure Gauge Meter, Fuel System Tester for Gasoline Engines, Accurate 0-100 PSI Measurement Kit with Braided Hose and Adapters for Auto Diagnostics

Features:Made of quality material, ensuring high durability for long time use.The fuel pressure gauge is used to measure the pressure of the fuel supply system and determine the operation of the fuel system components such as the electric gasoline pump and the oil pressure regulator.It can delivers vehicles' highest performance, with long life and highly reliable operation.A proper fuel pressure is critical at full throttle to prevent lean conditions.It is a dedicated tool for inspecting and troubleshooting the fuel system.Specification:Condition: 100% Brand NewMaterial: ABSColor: As picture shownConnection method:Install the fuel pressure gauge, disconnect the fuel high pressure common rail and the oil pipeline connection, and connect the fuel pressure gauge tee in series for measurement. From the measured values, it is easy to judge the operation of fuel system components such as electric gasoline pumps and oil pressure regulators. Measurement:(1) After the 5s automatic pumping of the electric gasoline pump, observe the fuel pressure on the oil pressure gauge. The normal oil pressure is about 300KPa. If the oil pressure gauge is swung around 300KPa, the oil pressure regulator works normally. After measuring the end of the initial oil pressure for 5 minutes, observe the fuel system to maintain the pressure indicated by the oil pressure gauge.Should not be lower than 147KPa. If the oil pressure is too high, check whether the oil pressure regulation road is working properly; if the oil pressure is too low, check the electric gasoline pump to maintain the pressure, the oil pressure regulator to maintain the pressure and the injector to leak.(2) Measurement of fuel pressure during engine operation.Start the engine and run at idle speed. Observe that the fuel system pressure indicated by the oil pressure gauge should not be lower than 250KPa. Otherwise, check the vacuum gauge for leaks or wrong insertion. Press the accelerator
