You're looking for an SVT focus pump. You should be able to get one from any Ford parts counter. Optionally, steeda sells a high flow stock replacement and my friend at SpeedConcepts sells focus and aviator pumps pretty cheap:

You're welcome.
Keep in mind that the aviator pump works too but is higher flowing than is usually needed.
