some people tap their waterpump for the steam tube to connect to, but we prefer to install that in our radiators. You are more likely to have a waterpump go bad than a rad, and if you are out away from home when it happens, the odds of you having a drill and tap in the truck is unlikely. We include them in all LS conversion radiators at no charge, unless the customer doesn't want the port.
