Abstract
A fuel system including first and second tank portions communicating with each other such that the first and second tank portions have a substantially equal vapor pressure, first and second fuel pumps in the first and second tank portions, respectively, and a crossover fuel line for transferring fuel in either direction between the first and second tank portions, the direction of transfer depending on the relative level of fuel in the first and second tank portions. Respective first and second shuttle valves control the direction of fuel flow through the single crossover line to maintain substantially equal fuel levels in both bifurcated portions until the tank is empty. First and second jet pumps communicate with the crossover fuel line and provide the suction needed for fuel transfer.
