A tank fitting assembly for an inlet/outlet port in a tank wall. The tank fitting assembly includes first and second fitting elements which are respectively mountable to an interior surface and an exterior surface of a tank and in registry with a drain opening in the tank wall. Stand-offs furnished on the underside of the body of the first fitting element create a gap between the underside of the element body and the tank wall. The gap serves as a fluid passageway, thereby allowing fluid to empty from the tank by passing along the bottom wall of the tank to the tank wall drain opening and then through a drain hole in the second fitting element. The connectors used to connect together the first and second fitting elements extend through bores provided in the first fitting element, through the tank wall, and through bores provided in the second fitting element. Plugs mountable to the heads of the connectors fit within cavities in the first fitting element in which the connector heads reside when installed, and the plugs provide fluid tight seals with the first fitting element to prevent fluid in the tank from reaching the connector heads. A method of providing a tank with a tank fitting assembly is also disclosed.
