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 universal fuel pressure gauge meter delivers precise readings from 0 to 100 PSI (approximately 690 kPa), allowing you to accurately assess fuel system performance. Use it to test electric gasoline pumps, oil pressure regulators, and injectors by measuring initial pressure, operating pressure at idle and full throttle, maximum system pressure, and pressure after engine shutdown.
• Complete Diagnostic Kit: The fuel pressure tester gauge comes with a comprehensive set of accessories including a braided hose, metal linkers, plastic installers, white adapters, metal hoops, gaskets, and a storage box. This complete kit enables quick connection to most fuel rails or test ports without leaks, making troubleshooting efficient for both professionals and DIY mechanics.
• Versatile Application: Designed for gasoline-powered vehicles, this fuel pressure gauge is ideal for diagnosing lean conditions, hard starts, poor acceleration, or stalling issues. It works across a wide range of cars, trucks, and SUVs with standard fuel injection systems, helping home users and auto technicians verify if the fuel supply system operates within manufacturer specifications.
• Durable ABS Construction: Built with high-quality ABS material, this fuel pressure meter ensures long-term durability and resistance to fuel exposure and workshop wear. The robust casing protects internal components during frequent use, while the clear dial face allows easy reading even in low-light engine bays.
• Easy Installation & Storage: The fuel pressure tester includes step-by-step measurement protocols—simply disconnect the fuel line, install the included T-fitting in series, and connect the gauge using the provided adapters. After use, all components neatly fit into the included plastic storage box, keeping your tools organized and ready for the next diagnostic job.
