Scag 484242 Seal, Fuel Gauge

What It Is

The Scag 484242 Seal, Fuel Gauge is an OEM replacement seal for the fuel gauge assembly on Scag commercial walk-behind mowers and zero-turn riders. It prevents fuel leaks and keeps the gauge seated properly in the fuel tank.

Fitment & Compatibility

• OEM part: Genuine Scag, not aftermarket. Fits Scag models using a fuel gauge in the tank top (e.g., many Turf Tiger, Cheetah, and Wildcat models).
• Check your model number: Verify your Scag mower’s model/serial number against the Scag parts diagram for the fuel tank assembly. This seal is specific to the gauge, not the tank cap.
• Measurements: Seal is roughly 1.5” OD, 1” ID, and 0.125” thick (rubber gasket). If your gauge housing has a different size, this won’t seal.
• Not universal: Does not fit other brands (John Deere, Exmark, etc.) without adapting the tank or gauge.

Key Things to Know

• Quality: OEM rubber seal – holds up to fuel and UV exposure better than generic O-rings. Expect years of service.
• Installation difficulty: Easy – remove gauge retaining ring, swap old seal for new, reinstall. No special tools.
• Common gotcha: Old seal often hardens and cracks, causing a slow fuel leak that’s easy to miss. Replace if you smell fuel or see dampness around the gauge.
• Price point: $22.48 is typical for an OEM Scag seal. Aftermarket alternatives are cheaper but may not fit as tightly.

Should You Buy It

Buy it if your Scag mower’s fuel gauge is leaking or the seal looks cracked/dry. It’s a simple fix that prevents fuel loss and fire risk. Skip if you don’t own a compatible Scag model or if the leak is from the tank cap or fuel line.
