the fuel filter is very easy. It'll most likely be on the firewall, shaped sorta like a black can of tuna with two hoses attached to the top.
Take the gas cap off, then unscrew the big bolt on the fuel filter. Have a shop rag over the bolt when you do this because fuel could spray.
Once the pressure's gone, unscrew both fuel lines, and then unbolt the filter from its mount. Reinstallation is the reverse of disassembly.
Do this in a well ventillated area or you'll get high from the gas fumes
