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 (0–640 KPa), allowing you to accurately test electric gasoline pumps, oil pressure regulators, and fuel injectors. Use it to verify baseline pressure, running pressure, and pressure—critical steps in diagnosing lean conditions or performance loss at full throttle.
• Complete Diagnostic Kit: The fuel pressure tester includes a braided hose, metal linkers, adapters, gaskets, and a plastic storage box, giving you everything needed for quick installation between the fuel rail and supply line. No extra tools required—just connect in series to start troubleshooting your vehicle’s fuel delivery system like a pro.
• Versatile Vehicle Compatibility: Designed for gasoline-powered cars and light trucks, this fuel pressure gauge is ideal for DIY mechanics, auto technicians, and performance tuners who need reliable data to maintain engine efficiency, prevent misfires, or validate fuel system upgrades during maintenance or repair work.
• Durable ABS Construction: Built with high-quality ABS plastic and reinforced metal fittings, this fuel pressure meter resists vibration, heat, and fuel exposure under the hood. Its rugged design ensures long-term reliability even with frequent use in demanding garage or roadside diagnostic scenarios.
• Step-by-Step Testing Guide Included: Follow clear procedures to measure idle pressure (250 KPa), full-throttle pressure (300 KPa), regulator function, max pump output (490–640 KPa), and pressure retention (147 KPa for 30 minutes). This fuel pressure tester helps pinpoint leaks, weak pumps, or faulty regulators fast.
