Ford Mustang fuel filter

I'm not familiar with that model, but Ford did put, on a lot of models, the filter in front of the right rear wheel, up along the siderail, clamped to a small bracket. But I know that some models had it in the engine compartment also, older models.

I think Tarus is correct on this model. However, if you list your engine type I can see how many filters you have. If I am correct, some systems had as many as 4 filters in the system.
