Automotive V8 cooling systems typically use the pump to draw cooler water from the bottom of the radiator, push it through the block from the front, where it then finds its way through the heads, and returns to the radiator through the thermostat and top hose.
Straightliner59's hose routing appears to be correct for this kit pump, though it may be difficult to understand fully by someone not well-versed in engine cooling.
The large lower connection of the kit crank-driven pump would go to the lower radiator.
The two smaller connections are output, and would go to either side of the block where a stock water pump would normally bolt on.
Return hoses from the head faces, possibly connected to fittings installed at freeze-plug locations, are hot water and would go to the top of the radiator.
