I just picked up a 2004 GP GT1 that needed a water pump. I was going to purchase the ZZP $20 water pump (because it had good reviews), but I did not want to wait for it to be shipped. I order a new life time water pimp from Advanced auto (CARQUEST T2269), for $35.49 - 30% coupon $10.65 = $24.84 add tax $1.50 = $26.33

Anyway it looks as though the ZZP water pump has the same part number as the CARQUEST water pump!
