It's a fancier pump -- I suspect a three-chamber diaphragm pump
instead of centrifugal; Shurflo seems to be fond of
them.  Incidentally ShurFlo is considered the cheap low-class OEM
pump by the marine fraternity, so don't feel *too* bad about the
price.  :-)  Also, pay *careful* attention to any instructions about
disinfecting the tank -- Shurflo has been known to specify extremely
small amounts of bleach (half-teaspoon in 20 gallons of water sort of
thing) and state firmly that larger amounts will destroy the pump and
be considered abuse.  I don't know whether that applies to this
pump.  In fact IIRC this developed in correspondence with the factory
with regard to a failed pump in a Vanguard-class sailboat, so it
might be advisable to check directly with them if the instructions
aren't explicit.

The newer ones used a tiny little centrifugal pump hung from its
outlet hose inside the tank.  Mine was made by Coleman-Germany.  VW
wanted $125 for the little POS after I froze and burst it in '92, so
I stuck in a submersible bilge pump I had lying around and never
looked back.  And I recommend that (300 gph submersible bilge pump
for $15-20) for anyone looking to directly replace the in-tank
pump.  Output volume will be regulated by the hose and spigot
size.  The price is having to adapt the outlet spigot to a smaller diameter.
