A fuel equalizing method and system for equalizing the amount of fuel in a plurality of fuel tanks connected to a motor, such as the diesel engine of a truck, is described. The system includes an equalization valve having a first common passage with two fuel inlets connected to two fuel tanks and a fuel outlet connected to the motor. A valve actuator member is mounted in the first common passage for longitudinal sliding movement in response to unequal fuel pressure in the two fuel inlets sensed by two fuel pressure sensing elements, which may be spherical balls, connected to the actuator member. A second common passage is provided in the equalization valve with a return fuel inlet connected to the excess fuel outlet of the motor, and two return fuel outlets connected to the two fuel tanks. A pair of valve elements connected to the opposition ends of the actuator member are positioned in the second common passage to control the flow of return fuel through the return fuel outlets and thereby equalize the amount of fuel in the fuel tanks.
