I got my tunes and now want to change out my fuel filter and O2 sensors. I have a 2004 f150 new model. Where is the fuel filter located? I did a search to no avail. Anyone know which Bosch oxygen sensors I should get?

 

here's a couple of threads about the fuel filter with a few pics, use a Motorcraft FG-986B only
the filter is on the inside of the frame, on the drivers side

it's easy to change but you'll need a 5/16 line tool
