A leaking or corroded fuel tank forces you to refill constantly and risks fuel spills that damage your mower and yard. Repair Clinic provides genuine OEM MTD fuel tanks, caps, floats, screens, and container assemblies—all designed for your exact model. Quality replacement tanks restore reliable fuel delivery and prevent carburetor problems caused by contaminated fuel.
From pinhole leaks to cracked plastic and stuck filler caps, genuine MTD tank parts ensure safe, efficient fuel storage and delivery to your engine.

Pinhole rust holes, stress cracks in plastic tanks, and worn gaskets are common causes. Ethanol-blended fuels accelerate corrosion in metal tanks. Inspect the tank for visible damage and the cap gasket for hardening or cracks. A new OEM MTD tank and cap kit solves the problem permanently while maintaining model-specific fit and performance.
Drain old fuel completely, then flush the tank with fresh gasoline or carburetor cleaner. If sediment persists, remove the float assembly and screen, and use a soft brush or cloth to gently dab interior surfaces. For severe buildup, tank replacement is faster and more reliable than internal cleaning.
Tank size varies by model—check your owner's manual or parts diagram for specifications. Most MTD push mowers hold 1.5–2.5 gallons, while larger ride-on models hold 4–6 gallons. Using a smaller capacity tank risks running out of fuel mid-mow; verify your exact model before ordering.
Aftermarket tanks may fit loosely, use incompatible fuel line connections, or have incorrect vent holes. OEM MTD tanks help ensure compatible fit, proper fuel delivery pressure, and carburetor compatibility. Genuine parts protect your engine and reliable performance—a small investment that prevents costly repairs.

On MTD lawn mowers, look for the model number on a label or metal plate attached to the mower deck, engine housing, or frame. If the number is difficult to read, clear away grass and dirt, then copy every letter, number, and hyphen exactly as shown. Enter the complete model number in the Repair Clinic search bar to narrow the full MTD lawn mower catalog to parts made for your machine, not just items in the Tank & Container category. This number identifies the mower itself and helps match every associated part to its correct design. Fewer wrong orders mean a faster repair.
