>Dave,
Isn't the water finding its way to that hole as a result of going
through the bearing? If that is the case it should make no difference
at all since the seal failure is already done at that point.

Well, heck, I don't know. I just assumed they located the hole to allow
the water to exit the housing before it reached the bearings. Since all
seals leak a little bit, a trace amount of water will seep through the seal
and if it can exit a drain hole before it reaches the bearings the pump
will still enjoy a long, usefull life. It's been years since I looked at a
TR6 pump (which I assume is very similar to a Spitfire pump) but I seem to
recall the hole was closer to the bump section than the extension section.
