Abstract

A fuel line may include a hollow elongate body having a first end and a second end. A first sealing member located on the first end of the hollow elongate body may have a monolithic construction and include a base region and a sealing region. The base region may have a first material hardness and the sealing region may have a second material hardness, the second material hardness being less than the first material hardness. A first connector may be coupled with the elongate body and the first connector and the first sealing member may be configured to sealingly connect to a fuel injector.

Description

technical field [0001] The present invention relates to engine fuel systems, and more particularly, to fuel injectors and fuel lines. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Fuel lines may be used to connect the fuel injectors with a pressurized fuel supply (source). A fuel line can be sealingly connected to the fuel injector. For example, a sealing member located on one end of the fuel line may mate with a fuel injector connector. To ensure a proper seal between the surface of the sealing member and the surface of the fuel injector, the connector may be secured to the fuel injector connector with relatively high force. Such large forces can cause deformation of the sealing member and / or fuel injector. Contents of the invention [0004] This section provides an overview of the invention and is not a comprehensive disclosure of its full scope or all of its f...
