Why not have the dealer replace it? Is it out of warranty?
The filter head bolts to the firewall on a braket with two bolts. It has two rubber hoses attached for input and output of fuel and it has three electrical connections, one on the bottom of the filter and two on the front. You will need to screw the sensor out of the bottom of the old filter and put in on the new filter probably. If the system came with a new sensor still screw the old one out and save it as you may find use for it in the future. Also make sure you don't swap the hoses when you put them back on. Should be pretty simple. If you can plug the fuel lines with something as you take them off or clamp them then you will have more fuel in the lines when you purge tyhem and have less likelyhood of contaminants. Purge the system of air with the pump when you are done.
Probably couldn't easily remove the filter with the head not bolted down.
If they didn't replace the old one under warranty I am sure the feds would love to see it, to have it in their hands.
