An interchangeable additive injection apparatus provides a plurality of flow paths from one or more upstream additive tanks to one or more downstream fuel containers. A plurality of additive lines converge into an additive conduit at a manifold disposed within the apparatus. A plurality of valves associated with the additive lines are selectively opened and closed to isolate one of the flow paths. A metering device is disposed along the additive conduit for measuring the flow of additive therethrough. A reversible, multiple port housing surrounds at least the valves and manifold. In a forward orientation, a plurality of upstream ports are coupled to upstream additive tanks, and a downstream port is coupled to a fuel tank. By reversing the housing, the apparatus is placed in a reverse orientation wherein the upstream port is connected to an upstream additive tank and a plurality of downstream ports are connected to downstream fuel tanks. In either orientation, an expansion apparatus may be coupled to an expansion port on the additive injection apparatus to provide a number of additional ports and flow paths. A controller is coupled with the injection apparatus to monitor and control the associated pumps, valves and meters.
A control system for controlling the flow of additive along a plurality of flow paths that pass through a reversible injection apparatus located intermediate at least one upstream additive tank and at least one downstream fuel tank, wherein the injection apparatus includes a meter for monitoring the flow of additive therethrough and a valve associated with each of the flow paths, said system comprising:
