Okay, you have the unicorn car. Because it is a PZEV the pump is no longer available as a unit and no aftermarket assemblies exist. Instead, you get a pump kit that is just the pump, a new fuel sock, the tank gasket and the internal hose. You will need to remove the pump assembly then follow the directions included in the pump kit to replace just the pump. The images will give you the basics, it's pretty much, remove the pump assembly from the tank after cleaning around the retainer really well. Then you set the assembly down, release the electrical connector to the pump and release the fuel line from the top of the filter housing. Pull the pump up out of the pocket in the pump housing assembly. Reverse the process to install the new pump. Install the replacement tank seal and once you have it installed use the hose on the return side with the pump line blocked off to check for any leaks around the pump or lines. I usually just spray some soapy water around the ring and blow it into the pipes with the fill neck and vent plugged. That could prevent you from having an EVAP code once you put it back together.
The pump kit (# 19167186) is discontinued through GM. However, you can get an OE quality part from Delphi as part # FE0673 which is the same as the GM kit. It shows up cheapest at Rock Auto for $150-220 depending on when you order, they have a couple on closeout. Looks like NAPA and Advance also have it but for a higher price. Bosch also sells that pump but theirs is just a Delphi part in a different box. While you can get other brand pumps for a lower price, I really wouldn't suggest them. I've never had much luck with them lasting very long, but it's your call on that.
