right under the passengers seat. obviously on the outside. crawl under the rearand take a look. it's bolted to the underside of the body.
1.) open your gas cap.
2.) open hood and go to the big fuse box on pass. side. take out the fuel pump fuse.
3.) crank over the engine. it may start and then crap out or not ever start. just keep cranking for 5 seconds or so.
that should bleed any pressure that your fuel lines may have. don't forget to put that fuse back in before you start it back up, when you're done.
another thing to do is to do it in the morning before driving. that lets out alot of the pressure.
when you buy the filter, either buy the tool to get the clips out or buy 2 more clips. and a lot of fuel comes out when you unhook the quick-disonnects. not like gallons but more than you want all over you. so stay to the side when you do it.
