There is no DIY, but I can tell you how to do it.

Look under the passenger rear behind the driver seat.
Under there you will see a panel that has about 15 screws that need to come off.

Take that panel off and you will see the fuel filter.

Before you start take out the fuel pump fuse and start the car. Car will die. There will still be a lot of fuel in there so the job is messy.

Good Luck
