Pressure release

NOTE: The fuel system cannot be relieved of pressure manually, the high-pressure fuel system loses pressure as the engine cools down. When working on the high-pressure fuel system wait until the engine is cool or 5 minutes, whichever is longer, to allow the high-pressure fuel system pressure to bleed off and the fuel to cool.

With the key in the OFF position make sure fuel pump and sender unit is not running. Wait two minutes after pump has shut off for the low-pressure system to bleed off pressure.
After the repair is complete, bleed the fuel system. Refer to: Fuel System Bleeding .
