Universal Fuel Pressure Gauge Meter, Fuel System Tester for Gasoline Engines, Accurate 0-100 PSI Measurement Kit with Hoses and Adapters for Automotive 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

• Accurate Pressure Measurement: This fuel pressure gauge meter delivers precise readings from 0 to 100 PSI (up to 640 KPa), allowing you to accurately test electric gasoline pumps, oil pressure regulators, and fuel injectors. Use it to verify baseline, idle, full-throttle, and fuel pressure to prevent lean conditions and ensure optimal engine performance.
• Complete Diagnostic Kit: The fuel pressure tester includes everything needed for immediate use—1 fuel pressure gauge, 1 fuel pipe, 4 metal linkers, 1 braided hose, 2 black plastic installers, 2 white adapters, 2 metal hoops, 2 gaskets, and a durable plastic storage box—making on-the-spot fuel system troubleshooting fast and efficient.
• Wide Vehicle Compatibility: Designed as a universal fuel pressure gauge meter, this tool works with most gasoline-powered vehicles to inspect and diagnose fuel delivery issues. Whether you’re a professional mechanic or a DIY enthusiast, it helps identify problems like weak fuel pumps, leaking injectors, or faulty pressure regulators.
• Durable ABS Construction: Built with high-quality ABS material, this fuel pressure gauge ensures long-lasting durability and reliable operation under repeated use in garage or roadside conditions. The robust design resists cracking and maintains accuracy even after frequent pressure cycling and exposure to fuel vapors.
• Step-by-Step Testing Guide Included: Follow clear procedures to measure initial pressure, operating pressure at idle and full throttle, maximum system pressure, and pressure after shutdown. With this fuel pressure tester gauge, you can confidently assess if your fuel system maintains proper pressure—critical for engine efficiency and avoiding damage.
