Where is the pressure release valve on a Chevy Tahoe?

The pressure release valve on a Chevy Tahoe is typically located on the fuel rail, which is situated on top of the engine. It is a small metallic valve that can be identified by its Schrader-type design. To relieve fuel pressure, you can press the pin in the center of the valve, but it's important to take precautions to avoid fuel spray. Always refer to the owner's manual for specific instructions related to your model year.
