I have a white insinkerator hot water dispenser that I only want to change the color to stainless. The tank is fine. Do you sell only the spout?

Yes we do have a hot water dispenser model that is sold without the tank.   That model is the FGN1100SN you may view this model on our web site, by typing in the sku# in the search box on the upper right hand side of the site.  
  Please note some of the older model tanks are not compatible with the faucet only.
