This might be a dumb idea but could you just take the guts out and plug the shaft hole and use an inline electric pump? I thought about running the mech. pump and having an inline electric pump to cool between races or to avoid the "heat sink" effect but Meziere said I would have to run the electric all the time. An electric kind of scares me on long trips unless I had a spare. The mech. pump I can buy anywhere.
