How do you replace the fuel filter located on a 2003 Ford Focus?
You need metric wrenches, I believe a 6mm and a 10mm, socket and 4" extension. It is on the right side up by the gas tank back by the right, rear door (if it's a 4-door. If it's a 2-door, it'll still be in that general area). It's about 2" in diameter and about 3" long and is bolted to the body/frame. Once you unbolt it you can see the rest. You have to change the mounting strap from the old one to the new one. Let us know how you make out.
The cabin air filter on a 2003 Chevy 2500HD pickup is located on the passenger side under the glove compartment. To replace it, first remove the two screws on the kick plate under the glove compartment. Remove the kick plate. Then, unclip and swing the filter housing cover to the right. Remove the filter by pulling straight down. Insert the new filter, and reassemble in the reverse manner.
