Cub Cadet Cub Cadet 3X 26 TRAC IntelliPOWER 357cc Three-Stage Snow Blower MECH-FUEL-LEAK Error Fix: Fuel Leaking from Snow Blower — Fire Hazard

Error code MECH-FUEL-LEAK on the Cub Cadet Cub Cadet 3X 26 TRAC IntelliPOWER 357cc Three-Stage Snow Blower means: Fuel Leaking from Snow Blower — Fire Hazard. Gasoline is leaking from the snow blower. This is a serious fire hazard. Stop the machine immediately, close the fuel shut-off valve, and do not operate until repaired. Common leak locations: (1) Fuel shut-off valve — the most common leak point. The valve seal deteriorates or the valve does not fully close. Replace the valve. (2) Fuel lines — the rubber fuel lines crack and harden from cold temperatures, fuel exposure, and age. Inspect all lines and replace any that are cracked, hardened, or swollen. (3) Carburetor bowl — the bowl gasket deteriorates or the float needle valve is stuck open, causing fuel to overflow. Rebuild or clean the carburetor. (4) Fuel cap seal — the cap gasket deteriorates and leaks, especially when the tank is full. Replace the cap. (5) Fuel tank — cracks from impact or UV degradation. On some models the tank is replaceable; on others, fuel-safe epoxy may work for small cracks. (6) Primer bulb — a cracked primer bulb leaks fuel. Replace ($5-$10). Always close the fuel shut-off valve after each use to prevent carburetor flooding during storage.
