The replacement pump I noted actually stated that you have to change the 2 studs/with fixed hex head bolts on the back of the original pump and transfer them to the new pump and also the fitting change from the new to the old, can be made, from the old male type connector to the female from the new pump. The studs are used for the bottom of the pump mounting and the adjustment in the slotted 409 pump bracket that attaches to the exhaust manifold and the front of the head. The new pumps do have a shorter pipe off the back of the pump(for the hose with no end on it ) than the original pumps.
I have at 3 or 4 female connectors to the pumps, that I have removed from other pumps ( I don't remember if they are from old or new replacement pumps).
That hose set looks to be the same hose set I have for my Borgenson 600 series pump. My Borgenson PS pump on the frame is made to clear the 4 core radiator in my 409. I am running one hose under the Borgenson PS pump and the so its long enough to reach the back of the pump on the motor. The other hose might run right next to it or around the frame.
