Abstract
A vehicle chassis with at least two fuel tanks with an engine engaged to the chassis structural member. Each of the fuel tanks has fuel level detector or sender. The level senders are engaged to an electronic controller. Each of the tanks has fuel draw line from it. The system uses a single control valve to equalize the fuel tank levels by use of a dual draw single return system. The system is split into a primary and secondary tank. The fuel level senders send information to an electronic controller generating a signal to the solenoid or control valve when a specific fuel level difference exists. Activating the solenoid or control valve from closed to open, located in the draw side fuel line from the secondary tank, fuel is drawn from both tanks. The return goes only to the primary tank. When the levels are equalized, the electronic controller sends signal to the control valve to close.
