Universal Fuel Pressure Gauge Meter, Fuel System Tester for Accurate Pressure Measurement, with Durable Construction for Gasoline Pump and Regulator Diagnostics

Features:Constructed from high-quality material to ensure exceptional durability for extended use.This fuel pressure gauge measures the pressure within the fuel supply system, helping assess the performance of key components like the electric gasoline pump and oil pressure regulator.It supports peak vehicle performance with reliable operation and a long service life.Maintaining correct fuel pressure at full throttle is essential to avoid lean running conditions.This tool is specifically designed for inspecting and diagnosing issues in the fuel system.Specification:Condition: 100% Brand NewMaterial: ABSColor: As picturedConnection method:To install, disconnect the high-pressure common rail and fuel line, then connect the fuel pressure gauge tee in series for measurement. The resulting readings make it straightforward to evaluate the functionality of components such as the electric gasoline pump and oil pressure regulator.Measurement:(1) After the electric gasoline pump automatically primes for 5 seconds, check the reading on the oil pressure gauge. Normal pressure should be around 300KPa. If the gauge fluctuates near 300KPa, the oil pressure regulator is functioning correctly. After recording the initial pressure, wait 5 minutes and verify that the system holds pressure—this value should remain above 147KPa. If pressure is too high, inspect the oil pressure regulator circuit; if too low, examine the electric gasoline pump’s ability to hold pressure, the regulator’s sealing, and potential injector leaks.(2) Measuring fuel pressure while the engine runs: Start the engine and let it idle. The gauge should show a fuel system pressure no lower than 250KPa. Otherwise,
