This is a genuine fuel tank assembly that is designed to be used with select gas-powered pressure washers. The fuel tank assembly is responsible for holding the gas to operate the engine, using fuel lines to run the fuel back and forth between the engine and the fuel tank. This is a durable metal part, but over time it can become corroded, dented, or otherwise damaged due to impacts or even regular everyday use. Damaged fuel tanks can leak and lead to fuel waste or even run the risk of creating a fire hazard. This is a genuine replacement fuel tank that is manufactured to OEM standards and serves as an exact replacement for compatible machines. It can be used with Generac generators, and is compatible with dozens of models. It is important to drain the fuel system and disconnect the spark plug before beginning this repair, and always work in well-ventilated areas when working on engines and outdoor power equipment. This durable metal fuel tank is sold as an individual unit and does not include the hardware needed to secure the tank. It does include the fuel cap so that both are replaced at the same time.
