What i would do is buy this pump

Bosch Electric Intercooler Pump 317GPH 12V 0392022002: eBay Motors (item 350353417472 end time Jun-11-10 11:20:20 PDT)

and have the dealer install it if possible, much better than the oem pump. Its the same pump the SVT Ford vehicles use and Ive never heard of anyone having a problem
