Hello, I am trying to help a lady friend get her Craftsman GT6000 working. It won't start but I am trying to figure that out. What has me really confused is this. Last year, just before the extended warranty ended she had a sears tech guy work on it and he said it was fine. When I opened the hood I saw a hose coming out from behind the vacuum fuel pump. The hose is about 1/4 inch outside diameter and about 2 feet long. the other end of the hose is attached to nothing and has a screw in the end of it. Does anyone know what this hose could be and what it should be attached to? The fuel lines and vacuum hose that are suppose to be running to and from the pump are all in place.
