fuel pump?

I cant decide between between the focus pump and the walbro pump. I am supercharging my stang very soon. I have already bought a kit online. I have heard good things about both but Iam leaning tward the focus pump because its OE and it comes in the mongoose kit witch you already know is a bad *** kit. plz explain why one over the other thanks.
 
The Walbro pump is designed to work with a return style fuel system and not the returnless style systems used after 1999. The Warlbro pump will work, but I've seen their life spans cut short trying to meet the demands of the returnless system. I'd go with the SVT Focus pump if I were you and call it a day.
