It's so easy it's not even funny...
The fuel pump hatch is in your trunk.
Pull the carpet up and it'll be on the right side next to the seat.
Remove those bolts.
There will be a foam pad. hold onto that.
Next it's not a bad idea to pour some carb cleaner, etc on top of the fuel pump assembly's cover and let it sit for a minute or two to loosen it up.
Then pull that off.
Inside you'll see the fuel pump. It's completely self explanatory on how to remove and install the new pump.
Save your old pump.. if I remember right walbro pays for oem fuel pump core's...
