Abstract
Abstract A system for transferring gasoline from a tank truck to an underground storage tank provides recovery of vapor displaced from the underground tank by gasoline from the tank truck. The system includes a fill tube that is coaxially mounted inside and spaced from a riser tube extending from the underground tank to a manhole to provide an annular space between the tubes from the manhole to the underground tank. The fill tube extends downwardly in the storage tank to a bottom portion of that tank for submerged filling of the tank. The system further includes a novel fitting of two pipes with a unitary construction. At the bottom end portion of the fitting the two pipes are coaxial, rectilinear and spaced from each other to provide an annular space to communicate with the annular space between the riser tube and the fill tube. At that end portion of the fitting, the outer pipe is constructed to be mounted on a male adapter permanently mounted on the top end of the riser tube. The fitting is thus mounted for a gasoline transfer operation. That end portion of the inner pipe of the fitting is constructed to be received by the top end portion of the fill tube, when the fitting is placed on the adapter. The intermediate portion of one pipe of the fitting is curved or arcuate while the intermediate portion of the other pipe is straight. The intermediate portion of one pipe extends through a wall opening in the other pipe so that the other end portions of the two pipes of the fitting are spaced apart from each other. These two pipes of the fitting at that other end are constructed to be connected to two hoses. One hose, which is a gasoline fill hose, is connected at one end to the bottom of the tank on a tank truck while the other end of the fill hose is connected to the top end of the pipe of the fitting that is inside the other pipe at the bottom end portion of the fitting. The other hose, which is a vapor recovery hose, is connected at one end to a pipe on the truck that communicates selectively with the top portion of one of the tank compartments on the truck, while the other end is connected to the pipe of the fitting that is outside the other pipe at the bottom end portion of the fitting.
