Where is the fuel filter on a 2002 Saturn vue SUV? Also how difficult is it to change?

Its located under the car. Do yourself a favor pay $125 Total, to have it changed.. Call around and confirm the cost. OR! Jack up the rear of the car and support it with jack stands. Make sure the car is high enough for you to comfortably work underneath it and that it is secure. Don't be the idiot that kills themselves by dropping a car on your head.

Looks like under the car You Tube search and there is a video of how to do it. Hardest thing is the bolts that hold the bracket on could be rusted in there and the head breaks off them.
