SAE J2587_201903

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
