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 System Pressure Release
Turn ignition off. Disconnect the negative battery cable in order to avoid possible fuel discharge if an accidental attempt is made to start the engine. Install Fuel Pressure Gauge Adaptor (J-34730-262) to the fuel pressure connection on the fuel rail. Connect Fuel Pressure Gauge (J-34730-1A) to the fuel pressure connection. Wrap a shop towel around the fuel pressure connection while connecting the fuel pressure gauge in order to avoid spillage. Install the bleed hose into an approved container and open the valve to bleed the system pressure. The fuel connections are now safe for servicing. Drain any fuel remaining in the fuel pressure gauge into an approved container. Remove the fuel pressure gauge and adaptor.
