DEVICE FOR EXCHANGING A FLUID BETWEEN A FIRST AND AT LEAST ONE SECOND TANK

摘要

A multiple fuel tank arrangement for maximizing fuel delivery to a vehicle during off level operation. The system has a tank from which fuel is withdrawn and at least one additional tank located at approximately the same level. The tanks are connected by a transfer line and crossover line. The transfer line connects the bottom of the tanks and only allows fuel flow into the fuel withdrawal tank. Openings for the crossover line are positioned such that a large volume of fuel is trapped in the fuel withdrawal tank when the tanks are as different relative elevations during off level operation.
