This genuine Midwest Engine fuel line directs fuel into the carburetor, which creates the mixture of fuel and air that powers the lawn tractor or a lawn mower.Fuel lines are likely to suffer damage as a result of the dirt, debris, pebbles, and gravel that might be flung around in the air and onto the lawn mower or lawn tractor during use. If punctures, tears, rips, warping, or erosion of the part occurs, the fuel lines must be removed and replaced immediately. Operating a lawn mower or lawn tractor without a functional fuel line can impact fuel economy or even cause dangerous fuel leaks.

This replacement exhaust gasket is a certified genuine OEM part for a lawn tractor engine. This gasket helps to seal off the exhaust from the carburetor. For an engine to run, it must first mix fuel with air to prepare the fuel for combustion. By sealing off the exhaust, this gasket allows for fresh air to enter into the carburetor from outside the engine rather than from the exhaust. Gaskets often degrade over time due to the stress of pressure and heat. If the exhaust gasket breaks its seal, it can affect the engine's overall performance. Be on the lookout for an especially noisy engine that doesn't provide as much power and is less fuel efficient. There may also be a noticeable burning smell coming from the engine. To replace the exhaust gasket, use a socket wrench and wrench set to remove the air filter and blower housings, then remove the exhaust manifold and switch out the gasket. This replacement exhaust gasket is compatible with engines made by Toro, Briggs & Stratton, Murray, Snapper, and Simplicity. It comes sourced directly from its original manufacturer and does not include any additional hardware.

This replacement vacuum is identical to the original vacuum hose that comes with the machine. The purpose of the vacuum hose is to maintain proper airflow through the engine. The part is made from durable plastic, but it could still require replacement. If the vacuum hose becomes damaged or cracked, it could allow air into other parts of the system, where it should not be. This could cause the engine to have problems running properly or not to run at all. Owners should make it a point to regularly check the vacuum hose, as well as other parts of the engine, to ensure that everything is in good working order. If an issue is found with the vacuum hose, it should be replaced immediately. The genuine OEM vacuum hose can be used to replace the hose on lawn tractors and other small engines. Compatible brands include Briggs & Stratton, Cub Cadet, Toro, Murray, MTD, and Simplicity. Owners should check their manuals before buying to ensure they are getting the proper hose for their make and model.
