Optimized Fuel Tank Sender Closure

Abstract

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 optimizeaThe closure system, durability and reliability with respect to—Vehicle SHED measurements—Fuel system / crash integrity—LEV – II useful lifebAssembly and service ease and reliabilitycPackaging of fuel tanks and their sending unitsdInterchangeability of sender closures between various fuel tank designs
