Looks like both of them might work, but i know for a fact this one will work. https://www.summitracing.com/parts/i...yABEgJ-vfD_BwE

OP, you want either Gates 18743 or Dayco 87629, just go with which ever is cheaper. Both of these will fit perfectly once you trim the longer end to match the shorter end.
The other Gates 18777 hose will not fit right because both inlet and outlet are the same diameter, which is not the case on the water pump.
The ICT Billet is the same as the two hoses I mentioned except its already trimmed, but there's really no need to pay $3 more for the same thing.
