GardenPal 791182612 Fuel Cap Compatible with MTD, Bolens, Ryobi, Yard Machine, and Craftsman, Replaces OEM 791-182612 Lawn Trimmer Replacement Parts

What It Is

The GardenPal 791182612 is a replacement fuel cap designed for gas-powered lawn trimmers and other outdoor power equipment. It seals the fuel tank to prevent leaks and evaporation, ensuring proper engine operation.

Fitment & Compatibility

Before buying, verify your machine uses OEM part number 791-182612 (or 791182612). This cap fits select MTD, Bolens, Ryobi, Yard Machines, and Craftsman trimmers, but not all models from these brands. Check your trimmer’s model number (on the engine shroud or under the fuel tank) and cross-reference with the cap’s listed compatibility—often found in the product description or seller’s fitment chart. Measure the cap’s outer diameter (approx. 1.5 inches) and thread pitch to match your tank opening. If your original cap has a tether, this replacement may not include one; verify if yours is tethered or not.

Key Things to Know

• Quality: Made from plastic with a rubber gasket; some users report the gasket can dry out over time, leading to leaks—check seal integrity after installation.
• Installation: Simple twist-on, no tools required. Ensure it’s snug but not overtightened to avoid cracking the cap or tank.
• Common Gotcha: If your trimmer has a vented cap (with a small hole), this cap may be non-vented—confirm your tank design. Using a non-vented cap on a vented system can cause fuel starvation or pressure buildup.
• Cross-Reference: Double-check that 791-182612 is the exact OEM part number on your old cap; some sellers list “compatible” but slight variations exist.

Should You Buy It

If you own a compatible MTD, Bolens, Ryobi, Yard Machine, or Craftsman trimmer and need a quick, affordable fix for a lost or cracked fuel cap, this is a solid choice. It’s not for vented systems or machines requiring a tethered cap, but for standard non-vented tanks, it works reliably at a low price.
