Introduction

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take

precedence.

1.1 Purpose/Material Description. This standard covers the material requirements of fuel filler and fuel filler vent

hoses (coupled or uncoupled), for use with gasoline fuel in automotive fuel systems.

Note: Fuel filler hoses for diesel and biodiesel applications are specified in GMW1 5605.

1.1.1 For use in non-conductive environments, all layers of the hose shall be non-conductive. Conductivity or non-

conductivity of filler hose constructions A, B, C, I, J and K shall be specified on part drawing. Filler hose constructions

D, E, F, G, H, and L are conductive, and shall meet the conductivity requirements of Appendix A, Table A2.

1.1.2 The material content of the hose, permeability and stiffness of the hose are defined by the Construction and

Reinforcement designations for the hose. The Construction and Reinforcement designations for the hose together

define the “Type” for the hose. Hoses of construction A, B, C, F, G and H are suitable for applications subjected to

maximum continuous operation temperatures of 90 °C with intermittent operation at temperatures up to 1 1 0 °C

maximum. Hoses of construction D, E J and K are suitable for applications subjected to maximum continuous

operating temperatures of 1 00 °C with intermittent operation at temperatures up to 1 25 °C maximum. Hoses of

construction I are suitable for applications subjected to maximum continuous operating temperatures of 1 25 °C with

intermittent operation at temperatures up to 1 50 °C maximum. In general, lower fuel permeating hose constructions

result in stiffer and less flexible hoses.

1.2 Symbols. Not applicable.

1.3 Applicability. Fuel filler and fuel filler vent hoses (coupled or uncoupled), for use with gasoline fuel in automotive

fuel systems.

1.4 Remarks.

1.4.1 Classification. Materials covered by this standard are divided into several sets of constructions and

reinforcement categories. The hose is defined as “GMW15349 Type XY”, where “X” refers to the construction of the

hose and the “Y” refers to the reinforcement of the hose.
