If you choose to replace the connector, get one made of machined brass rather than stamped. It will last longer than the hose, no matter how you abuse it.

When you buy hoses, look at both ends, get one where BOTH ends are machined brass. Also make sure that the barb (the part that goes inside the hose) is a solid part of the connector; I've seen some with machined connectors and stamped barbs. It's OK for the ferrule (the crimp ring on the outside) to be stamped.

A good quality hose will last a lifetime. The Sears Craftsman black rubber hose is a good option (though it can leave black marks).
