Full Description

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

The closure system, durability and reliability with respect to

Vehicle SHED measurements

Fuel system / crash integrity

LEV – II useful life

Assembly and service ease and reliability

Packaging of fuel tanks and their sending units

Interchangeability of sender closures between various fuel tank designs
