Under vehicle near fuel tank/rear wheel area. no its on the passenger side in front of passenger seating area. its a bit of a pain to get to because its on fire wall at passengers feet i know i spent to days looking for mine every one said tit was in the rear driver side that's not for caddy its true for Buicks also be careful of nylon full line not to kink it. I found out that the fuel filter is located on the rear Driver side. I just changed one out today on my sister's Cadillac. If you look under the car on the front rear wheel drivers side, you will see the fuel filter. You may have to look closely. It is somewhat tucked away to where I almost didn't see it. IMPORTANT! You will have to work quickly from getting the old fuel filter out and placing the new one in. Even though it has an electric fuel pump, gravity will still pull down the gas and will pour on the floor. It would be a good idea to have an oil pan or some type of pan close by to catch the gas if you don't want it on the ground.
