I was recently told that there were 2 fuel filters that needed to be change on my car?
I had one changed about 10k miles ago. I think it was the main filter, under the passenger side by the rear wheel.
Where is the other one? How much would having it done cost?
Is it neede?

(I am finally on schedule, so that I can have a complete 30K mile service when I hit 120k miles..., everything has been sporadic since I got the car, I want it all to be more organized!)

Thanks everyone.
