There is a hose connection just above and behind the 2005 Chevy Venture LS. Three hoses of about 1" diameter come into this connection. The shortest hose connects to a tube that goes straight down behind the engine. That tube appears to have a plastic nozzle connected to the top of it which the hose fits over. That nozzle is broken off. Can it be ordered, or does the entire tube need to be replaced. How is the tube attached to the engine.

 

Pic would be helpful to answer. A lot of the plastic clips are available separately if is what I'm thinking it is.
