Abstract: A fuel system for an aircraft. The fuel system includes a fuel tank configured to contain liquid fuel. A non-extendable fluid line is coupled between an airframe member of the aircraft and the fuel tank. A sleeve assembly is coupled between the fluid line and an upper surface of the fuel tank. The sleeve assembly includes a sealing sleeve and an extension sleeve. The sealing sleeve is positioned around the fluid line forming a fluid tight seal therewith and having a non-sliding relationship therewith. The extension sleeve is positioned around the fluid line with a first portion of the extension sleeve having a sliding relationship with the fluid line such that increasing the distance between the upper surface of the fuel tank and the airframe member causes the extension sleeve to increase in length as the fluid line slides relative to the first portion of the extension sleeve.
