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

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

• Accurate Pressure Measurement: This fuel pressure gauge meter delivers precise readings from 0 to 100 PSI (up to 640 KPa), allowing you to accurately diagnose fuel system performance. Use it to test electric gasoline pumps, oil pressure regulators, and injectors by measuring initial pressure, idle pressure, full-throttle response, and pressure—critical for preventing lean conditions and engine damage.
• Complete Diagnostic Kit: The universal fuel pressure gauge comes with a braided hose, metal linkers, plastic installers, adapters, gaskets, and a storage box—everything needed for quick setup on most gasoline vehicles. Easily connect in series between the fuel rail and supply line to start troubleshooting without extra tools or complicated procedures.
• Professional-Grade Troubleshooting: Ideal for mechanics, DIY car enthusiasts, and auto repair shops, this fuel pressure tester helps identify issues like weak fuel pumps, leaking injectors, or faulty pressure regulators. Whether your engine hesitates at acceleration or won’t hold pressure after shutdown, this gauge provides clear data to pinpoint the root cause.
• Durable ABS Construction: Built with high-quality ABS plastic and reinforced metal fittings, this fuel pressure gauge resists fuel , vibration, and high-pressure stress during repeated use. The robust design ensures long-term reliability under garage or roadside diagnostic conditions without cracking or leaking.
• Comprehensive Testing Capabilities: This fuel pressure tester supports five key diagnostic procedures—static pressure, idle pressure, wide-open throttle response, regulator bypass test, and pressure check. With clear guidelines included, even beginners can evaluate if their fuel system maintains proper pressure (e.g., 250 KPa at idle, 300 KPa at full throttle).
