This is a genuine replacement fuel line with an in-line fuel filter. It is designed to work with a number of different small engines found on yard equipment, such as lawn mowers, tillers, and more. This part serves several critical purposes on the engine, including moving fuel from the tank to the combustion chamber. The in-line filter removes debris and contaminants from the fuel, helping keep the engine running smoothly. Fuel lines and fuel filters both wear out over time. Debris will eventually clog fuel filters, forcing a replacement. Fuel lines can become brittle through time, exposure to gasoline, and exposure to heat and the elements. Replacing this fuel line/fuel filter combo is simple. A pair of needle-nosed pliers is the only tool required. Simply pinch the clamps to open them, pull the fuel line loose from the nipples, and replace it with the new part. Note that this fuel line is designed for a range of Briggs & Stratton small engines found on common yard equipment, including Toro lawn mowers. It is an OEM part and is sold individually.
