A » To perform a fuel pressure test, connect a fuel pressure gauge to the test port on the fuel rail, start the engine, and observe the reading. Normal fuel pressure typically ranges between 30-45 PSI for most vehicles, but always consult your vehicle's service manual for specific values. Ensure all connections are secure, and take safety precautions, such as relieving system pressure and wearing protective gear, to prevent fuel leaks or injury.
