What is the standard fuel pressure?
1 Answers
The normal fuel pressure for a car is between 300kpa and 350kpa. It should be noted that the gasoline pressure may vary depending on the vehicle model, but as long as it is around 300kpa, it is considered normal, which is equivalent to 0.3MPa. Symptoms of insufficient gasoline pressure include: Lack of power when accelerating; Frequent stalling; Engine knocking. The method to test gasoline pressure is: Turn on the ignition switch without starting the vehicle; Unplug the fuel pump relay and use a dedicated jumper wire to connect the fuel pump circuit; After starting the vehicle, connect the fuel pressure gauge to check the engine's gasoline pressure value.
