Craig,
CH313 is the top hose, but I can only remember the number for an FJ bottom hose, which doesn't help. The last bottom hose I bought for the FC said it was the same as for a TX Gemini (best to check). Repco can get the hoses, but you need to tell them the part number because their databases don't go back that far. Otherwise, Rare Spares.
Water pumps are a different matter. You used to be able to get repair kits from places like Auto Surplus in Melbourne. I have wondered about buying a red motor pump and raiding it for the bearing and seal.
Use caution with aftermarket grey motor water pumps. In some cases, the bolt holes don't line up, and need enlarging. The shaft sticks out too far at the front - cut it off flush with the hub. And the hub subtly distorts the pulley. If you have a Dremel, you need to grind four shallow slots into the hub to clear the pressed ribs in the pulley. Or if you have a press and an original Holden water pump, swap the hubs over.

Thanks for the heads up Rob,
I have three original water pumps that have good impellors etc - so if I can find repair kits I am good to go. I have searched previously with no luck but will have another crack.
Really appreciate the advice on fitting up the after market pumps - that is invaluable information that I will note in the workshop manual for future reference!
Cheers n Beers
