You should have the fuel filter on the engine pass side on the front it is a big bracket behind the alternator the filter is most times white and could have an aluminum bowl on the bottom (this You keep) or may just be a one piece filter in which case You just trow the hole thing away.

The fuel filter You can get on-line at filter1.com and the part #33617.
