    • A fuel transfer apparatus (10) for providing fuel to a vehicle engine from a plurality of fuel tanks. A transfer pump (22) is positioned intermediate a pair of fuel tanks (24, 26) and is operable to transfer fuel therebetween. Fuel is provided to the engine from a first one of the two fuel tanks. Excess fuel is returned to the first one of the two fuel tanks. When the level in the first fuel tank is less than the level in the second fuel tank by a predetermined amount, the transfer pump transfers an amount of fuel from the second fuel tank to the first fuel tank. Fuel level sensors (32) are utilized to monitor the level of fuel in the two fuel tanks and report to a microprocessor (40) which controls the transfer pump. The microprocessor utilised to control the transfer pump may be incorporated into the transfer pump, may be a stand alone microprocessor, or may comprise an existing vehicle circuit board such as, e.g., the electronic control module (ECM). A three-way valve (54) may be incorporated into the transfer pump so that the transfer pump can be additionally utilised to provide a priming feature for an engine driven fuel pump.
    • 一种用于从多个燃料箱向车辆发动机提供燃料的燃料输送装置(10)。 输送泵(22)位于一对燃料箱(24,26)之间,可操作以在其间传递燃料。 燃料从两个燃料箱中的第一个提供给发动机。 过多的燃料返回到两个燃料箱中的第一个。 当第一燃料箱中的液位小于第二燃料箱中的水位预定量时,转移泵将一定数量的燃料从第二燃料箱传送到第一燃料箱。 燃料液位传感器(32)用于监测两个燃料箱中的燃料水平并报告给控制输送泵的微处理器(40)。 用于控制转移泵的微处理器可以结合到转移泵中,可以是独立的微处理器,或者可以包括诸如电子控制模块(ECM)之类的现有的车辆电路板。 三通阀(54)可以结合到输送泵中,使得输送泵可以另外用于为发动机驱动的燃料泵提供起动特征。
