2002 GP fuel question

I'm trying to change the fuel filter on my 2002 Grand Prix and am having trouble releiving the pressure. Any ideas? Also I cannot find a service book(Haynes or Chilton) for this year.Thanks!

Either pull the fuse for the fuel pump and turn the car over for a few seconds, or using a towel underneath to catch any fuel, depress the schrader valve in the fuel rail for a few seconds until no more fuel comes out
