[TR] Alloy Water Pump

[Bob Danielson]

And one nice Lister just offered me a brand new 6 blade impeller at a very
reasonable cost. :-)

I think I've already seen BFE mentioned as a source.  So I only want to add
that it's the 6-blade impeller that increases water flow, not the alloy
pump.  Don't know if he still does, but Ken (at BFE) used to sell the
6-blade installed on a cast iron pump considerably cheaper than the alloy
pump.

Only advantage of alloy, AFAIK, is that it saves a pound or two.  At least
partially in your wallet !

BTW, since the pressure cap is at the point water enters the radiator, the
pressure in the radiator is not increased by additional water flow.  If
anything, the pressure at the bottom outlet is decreased (because of
increased drop across the radiator).
