Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Pressure Relief
Fuel that flows out at high pressure can cause serious injury to the skin and eyes. ALWAYS depressurize the fuel system before removing components that are under high fuel pressure.
- Install a scan tool to the vehicle and command the fuel pump relay OFF, allowing the low pressure fuel pump to shut off.
- Start the vehicle and allow the engine to idle until the engine stops. The engine will stop in approximately 20-30 seconds.
- Turn the ignition OFF.
- Using the scan tool, verify that there is little to no fuel pressure, if there still is fuel pressure repeat step 2.
If a scan tool is not available, WAIT at LEAST 2 hours after the engine has been run, before removing the high pressure fuel line.
