Tube,3X6X90 92190-2174

The return fuel line is used to transfer fuel from the carburetor, back to the fuel tank. This fuel tube is designed for use with trimmers and is made of high-quality polymer and measures approximately 3.5-inches (90cm) in length, .12-inches in inner-diameter (3mm) and .24-inches in outer-diameter (6mm). This tube does not come with any securing hardware and is sold as an individual part. Although this tube is known for its strength to most chemicals like gasoline, prolonged exposure to UV rays, extreme cold or hot temperatures and certain fuel additives can cause this tube to degrade quicker. If you notice a reduction in flexibility and clarity of the material, and general brittleness to the tube, replace it immediately. Prolonged use of a fuel line that needs replacing can cause issues such as fuel leaks and engine performance issues resulting from poor fuel flow or contaminated fuel. To replace this tube for your trimmer, drain the fuel from your trimmer before simply removing it from the carburetor and grommet, and any securing hardware. You may require a push tool to install the new tube, and that should be done with the appropriate hardware to secure it to the carburetor and fuel tank grommet.
