How do you relieve the fuel pressure on a 2002 Ford Taurus to change a fuel filter?
First loosen the gas cap and relieve any pressure in the tank.
Now look on the fuel rail for a schrader valve and push it to
relieve the pressure. It will look like a tire valve. If you find
none, then just be prepared for a spray of fuel when you disconnect
the fuel line. Wrap it with a rag to prevent the spray.
