Universal Fuel Pressure Gauge – Precision Diagnostic Tool for Gasoline Pump & Regulator Testing with Rugged Build

Features:Crafted from durable materials for extended service life in tough automotive conditions.This fuel pressure gauge measures fuel supply system pressure to assess performance of key components like the electric gasoline pump and oil pressure regulator.Supports peak engine performance through reliable, consistent operation over time.Maintaining correct fuel pressure at wide-open throttle is essential to avoid dangerous lean running conditions.Engineered specifically for fuel system inspection and troubleshooting.Specification:Condition: 100% Brand NewMaterial: ABSColor: As picturedConnection method:Install the gauge by disconnecting the high-pressure fuel rail and oil line, then insert the fuel pressure gauge tee inline for accurate measurement. Readings clearly indicate whether the electric gasoline pump or oil pressure regulator is functioning properly.Measurement:(1) After the electric gasoline pump auto-primes for 5 seconds, check the gauge. Normal pressure reads ~300KPa. Stable fluctuation around this value confirms a working regulator. After 5 minutes post-shutdown, residual pressure should stay above 147KPa. Excessively high pressure suggests regulator issues; low pressure points to pump weakness, regulator failure, or injector leaks.(2) With engine idling, system pressure must remain at or above 250KPa—any lower indicates a potential fault.
