Water pump cover to heater barb size

[misterp]

Does anyone know the sizes/ spec for the water pump housing to heater hose barb?
The one I have is a bit corroded so I'd like to replace if I can?
Rimmer's etc. don't seem to list it for the sprint or TR7.

I think the hose size is 13mm/1/2" but any idea of the thread size in the housing?

Thanks

There are two sizes,
the early one is the same as the T2000/Viesses/GT6 water pump hosetail,
the later type is common to the TR7.

The early type is a UNF screw (5/8"UNF I think?) whereas the later is a (tapered) BSP. Both are for 13mm hoses.
