本规程描述了与燃油液位传感器和燃油输送系统一起使用的燃油箱盖的推荐性能要求。它提供了确保油箱和燃油泵/发送器关闭系统之间互换性和兼容性的指南，而无需指定特定的关闭系统设计。这些系统可用于塑料或金属制成的刚性油箱系统。 具体设计的完整细节应由客户和供应商共同协商确定。 选择尺寸和性能要求进行优化 a、 封闭系统、耐久性和可靠性 -车棚测量 -燃油系统/碰撞完整性 -LEV-II使用寿命 b、 装配和维修的简易性和可靠性 c、 燃料箱及其输送装置的包装 d、 不同燃油箱设计之间发送器密封件的互换性

This practice describes recommended performance requirements of fuel tank closures used in conjunction with fuel level senders and fuel delivery systems. It provides guidelines that assure interchangeability and compatibility between fuel tanks and fuel pump/sender closure systems without specifying a specific closure system design. These systems may be used in rigid fuel tank systems made of plastic or metal. Complete details of specific designs shall be established by mutual agreement between customer and supplier. The dimensions and performance requirements are selected to optimize a. The closure system, durability and reliability with respect to - Vehicle SHED measurements - Fuel system / crash integrity - LEV - II useful life b. Assembly and service ease and reliability c. Packaging of fuel tanks and their sending units d. Interchangeability of sender closures between various fuel tank designs
