Is ZR1 water pump different than others and how much it usually cost?

Need to get this fixed ASAP.

The usual suspect is the pump shaft seal. The pump is ZR-1 specfic and can be pricey depending on where you get it. I chagned mine a year ago and paid about $150.00 for a NOS pump. Check Corvette Central, they have AC Delco pumps for the ZR-1. Make sure it comes with a gasket.
