I replaced my raw water pump on my 2005 Searcy 270 Amberjack with Mecruiser 496 Magazine engine. One of the air fittings on the pump was cracked. I replaced it. Now I have a black hose coming from the top of the pump (above the air fittings) and I don't know where it is supposed to go. I did not disconnect it and I don't see and open fittings. Any ideas or references? It's not shown on the Sea Ray manuals that I have.
