How do you release pressure in gas tank in a miata?

To release pressure in the gas tank of a Miata, first ensure the vehicle is turned off and parked in a well-ventilated area. Open the fuel filler cap slowly to allow any built-up pressure to escape. If you're working on the fuel system, you can also relieve pressure by removing the fuel pump fuse and running the engine until it stalls, which will use up the fuel in the lines. Always take precautions when handling fuel.
