- the compact housing construction features the utilization of first and second axially disposed housing parts which together form a cylindrical housing envelope for enclosing the stack-up of pump unit parts.
- the housing parts are sized and shaped to form complementary inner and outer diameters with a seal groove and a locking groove formed therein.
- a seal ring is situated in the seal groove and a locking ring in the locking groove, thereby to retain the housing parts in sealed-together assembly when one of the housing parts is inserted within the other of the housing parts.
- one of the housing parts has formed thereon means providing an inlet opening for connection to a top mounted or a remote mounted reservoir.
- the inlet opening intersects a flat mounting surface so that a top mounted reservoir may be situated directly superjacent the pump housing.
- a boss providing the inlet opening has a nipple connection for coupling to one end of a flexible conduit.
- the other end of the flexible conduit is connected to a reservoir disposed at a location remote from the pump.
