Fuel Pressure Gauge
A tool used to measure the pressure in the vehicle's fuel system.
A fuel pressure gauge helps confirm that the fuel pump and pressure regulator are functioning correctly. Insufficient pressure can cause engine misfires or poor performance, while excessive pressure can flood injectors. Modern gauges include quick-connect fittings and adapters for various engines. By checking pressure readings against manufacturer specifications, mechanics can isolate fuel delivery problems early. Regular fuel system checks ensure reliability and fuel efficiency, especially in high-mileage vehicles.
