The pump appears to be available without buying the entire manifold (housing). So - if it ain't broke, don't fix or replace the manifold. I believe the 2014 manifold is different. Here's an excerpt from a 2017 thread addressing water pumps. Part numbers may have changed yet again.

Thanks for the question, fyreant. I can understand the confusion. We have made part number changes as we continuously improve our production and service parts. Your question asks about 2015 and later cars, but I thought I better talk about 2014’s also. We also have to distinguish between the water pump kit (pump and gasket) and Crossover assembly which includes the water pump and manifold (what I think you are referring to as a housing). For 2015 and later cars the most current part numbers are 12681259 (crossover assy) and 12683013 (pump). The pump and gasket are actually back-serviceable to 2014 model Corvettes as well. Although we may have had part shortages for these part numbers in the past, our system is currently showing availability for both right now. Note also these part number are good for both LT1’s and LT4’s.
For 2014 Corvette owners wanting the full crossover assembly, that part number is 12688645. This part is replacing the previously available 12679050. We have sold out of the old part number, but expect deliveries of the new part number next week. Based on outstanding orders, we will have more than enough stock to cover everyone.

Water pump on 14 is just the pump impeller, bearings and pulley, which bolt into the whole assembly. Easy to swap out. Mine lasted 24k miles before it went out, but the pump was only around $50 at autozone. I didn't go back with the GM one since it didn't hold up.

I heard that there's the design issue on 2014 model. Doesn't it?

No water pump issue that I know of. But note that the newer water pump kit is backward compatible. It is the manifold that's different. I didn't have any problems with my 2014 Z51.
