fuel filter location

The fuel filter is integrated in the in-tank fuel pump module. I don't think it's available separately and you'd have to remove the service cover in the floorpan above the tank and access it by pulling out the fuel pump module. Unless you have a fuel pressure problem, the filter is considered a non-maintenance item and would be replaced along with the entire module assembly when the pump fails.
