Abstract
A vehicle chassis with at least two fuel tanks with each of the fuel tanks having fuel level detector or sender. The level senders are engaged to an electronic controller. The individual tank draw lines from each tank come together at a control valve that has a single outlet that leads to an engine. The control valve can be open from one of the tanks at a time to the engine. An electronic controller takes the inputs from the fuel senders and compares levels between the tanks to control the valve. The system defaults or starts drawing from a primary tank and upon the level in the primary tank falling to a pre-specified amount below the level in a secondary tank, the electronic controller shifts the control valve to draw from the secondary tank or vice versa on a secondary tank level drop.
