looking for the short black pump assembly hose that clamps to the diswasher tub. it's the shorter black tube in this diagram, not the elbo'd one.

sears wants me to buy the whole assembly for $200. Mine popped off the tub and looks like the hose was cut by the tub-side crimp clamp. how can I just get the strait black rubber tube and clamp it on the assembly? It appears to be a stand-alone part.
