no special tools are required...a strap wrench makes it a whole lot easier to get the filter loose. Also, that tool from Merchant automotive isn't required, but it keeps you from messing up the water in fuel (WIF) sensor (I bought one of those). You can get the sensor out with some channel locks. As long as you make sure you get both seals off with the old filter and you bleed the system, you will have no issues. I have read where people have had problems after having the stealership change their filter since their filter head got messed up and they chased the problem for quite a while. The only other thing that you need to be careful with is the bleeder screw. Be fairly gentle with it and don't overtighten and crack it.
