Hello kngbush.
The filter is mounted inside the frame rail just ahead of the fuel tank.
Be cautious changing it because there is pressure in the lines.
I wrap a shop cloth around the fitting when undoing it.
Keep a good sized drain pan handy, keep any items away that could cause a spark or flame.
A fire extinguisher would be very good thing to have as well.

Most fuel filters on modern cars are located under the passanger seat,usually on the inside wall of the car.

SOURCE: replace low beam headlight on 2003 chevy trailblazer

when the hood is open there are two pins that have to be pulled. they have a 90 degree bent end that have to be rotated and pulled directly up. once both are pulled the headlight can be slid out and headlight changed.

Location of the fuel filter on a 2005 Chevy TrailBlazer

You dont have a external fuel filter. Its build into the fuel pump and is located inside the gas tank with it. It is designed to last as long as your fuel pump does.
