5022917 Fuel Gauge

What It Is

The 5022917 Fuel Gauge is an aftermarket replacement part designed to monitor fuel levels in lawn mowers, tractors, and other outdoor power equipment. It’s intended for gas tanks that use a standard 2-inch or 2-1/4-inch opening.

Fitment & Compatibility

Before buying, measure your fuel tank opening diameter – this gauge fits 2-inch (50.8mm) and 2-1/4-inch (57.15mm) holes. Check if your tank uses a grommet or threads; this gauge typically requires a grommet mount. It’s not OEM-specific but replaces many common models from brands like John Deere, Husqvarna, and MTD. Verify your tank depth – the gauge’s float arm length must match for accurate readings. If your tank has a curved or obstructed opening, ensure the gauge’s float arm clears it.

Key Things to Know

• Quality: Plastic construction is durable but can become brittle in extreme cold or UV exposure; consider storing indoors during winter.
• Installation: Easy – remove old gauge, insert new one with grommet (not included), and tighten. No tools required for most tanks.
• Common Gotchas: The float arm may bend during shipping – check and straighten gently before installing. If your tank has a non-standard opening, you may need an adapter ring.
• Accuracy: Works best with clear fuel; dirty fuel or sludge can cause the float to stick. Clean tank if needed.

Should You Buy It

Buy this if you need a simple, affordable replacement for a broken or missing fuel gauge on a standard residential mower or tractor. It’s a straightforward swap for DIYers, but skip it if your tank has an odd-size opening or you need a gauge with a fuel sender (this is a passive indicator only).
