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

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 (0–640 KPa), allowing you to accurately test electric gasoline pumps, oil pressure regulators, and fuel injectors. Use it to verify baseline pressure, operating pressure at idle or full throttle, and pressure after engine shutdown—critical steps in diagnosing lean conditions or performance loss.
• Complete Diagnostic Kit: The fuel pressure tester includes everything needed for immediate use: 1 fuel pressure gauge, 1 braided hose, 4 metal linkers, 2 white adapters, 2 black plastic installers, 2 metal hoops, 1 fuel pipe, 1 gasket, and a durable plastic storage box. This comprehensive setup ensures compatibility with most gasoline fuel systems without requiring additional tools.
• Versatile Automotive Use: Designed for mechanics and DIY car enthusiasts, this fuel pressure gauge is ideal for troubleshooting poor acceleration, hard starts, stalling, or check-engine lights related to fuel delivery. It works on a wide range of gasoline-powered vehicles, making it a must-have tool for home garages, auto repair shops, and performance tuning scenarios.
• Durable ABS Construction: Built with high-quality ABS material, the fuel pressure gauge meter resists cracking, , and fuel exposure, ensuring long-term reliability under repeated use. The robust design maintains calibration accuracy over time, so you can trust every reading during critical diagnostics or routine maintenance checks.
• Easy Installation & Clear Readings: The fuel pressure tester connects in-line by replacing the fuel rail connection with the included T-fitting, enabling real-time monitoring without complex modifications. The large, easy-to-read dial face provides instant visual feedback, helping you quickly identify abnormal pressure drops, regulator failures, or pump wear during engine operation.
