Water pump - repair or replace

I've been working on the 1937 pickup for a while. While underneath the truck, I noticed coolant seeping from the shaft of the left water pump. I have several options: buy a rebuild kit with a new seal, send the pump out to one of our expert rebuilders or buy a new pump advertised with new housing, ceramic seal, sealed ball bearings and new helical impeller for improved cooling. I'd like to try the rebuild but haven't done one but have seen Mart in England rebuild one and it doesn't look too bad. Questions: can the lower hose be removed/replaced without removing the radiator? Do I rebuild both on general principle or try to avoid fixing something that isn'r broke? Thanks for your input.

First tap on the pulley with a hammer and it may stop leaking. Sometimes a small piece of rust gets in there between the shaft and seal and causes the leak. Tapping with a hammer may dislodge it.
 
I'd rebuild them both. I'd send them to Haney.
Most likely they were both installed at the same time. If one is leaking, again, most likely, the other isn't far behind.
Heck, the radiator is drained, now is the optimum time.
Yes, you may R&R the hoses with the radiator installed. It's a pain in the butt job but very doable.
Boiling the hoses for a little time helps tremendously.

Agreed. Kind of like headlight bulbs. When one goes, the other is shortly behind.

Thanks for the boiling tip. Never thought of that, but makes perfect sense.
 
TJ, Kube, Tim and CAVictoria: thanks for the advice on the pumps and hoses. I'll contact Skip and see how busy he is these days. Probably very. Thanks again.

George, busy or not, is quite prompt. he's a good guy you can count on.
 
The fellow in CA is Daryl Fryer and also advertised in the V8 Times. When I lived in CA I sent my pumps to him and was very pleased. If Skip is backed up give Daryl a call .He is in Redlands -near Riverside.909-335-1418.
