2pc 594061 Fuel Tank Cap Compatible with B & S To&ro Crafts&man Lawn Mower Gas Tank Caps Replacement replaces 84004416, 597414

What It Is

This is a 2-pack of replacement fuel tank caps (model 594061) designed for Briggs & Stratton, Toro, and Craftsman lawn mowers. It seals the gas tank to prevent fuel evaporation and spillage during operation or transport.

Fitment & Compatibility

Before buying, verify your mower’s fuel tank cap is a twist-on type with a 1-3/4 inch (44mm) outer diameter. This cap replaces OEM part numbers 84004416, 597414, and 594061. It fits many Briggs & Stratton engines (e.g., 500–900 series) and Toro/Craftsman walk-behind mowers with plastic fuel tanks. Do not assume universal fit—measure your current cap’s diameter and thread pattern. Cross-check your mower’s model number against the listed OEM replacements online.

Key Things to Know

• Build quality: Caps are plastic with a rubber gasket; the gasket may compress over time, but the 2-pack gives you a spare.
• Installation: Tool-free, hand-tighten until snug. Over-tightening can crack the cap or tank.
• Common gotcha: Some users report a loose fit on older tanks with worn threads—test the seal by shaking the mower after install.
• Vent: These caps are non-vented (sealed); if your mower requires a vented cap (e.g., for gravity-fed fuel systems), this won’t work.

Should You Buy It

Buy this if you need a quick, affordable replacement for a worn or lost cap on a common Briggs & Stratton, Toro, or Craftsman mower. It’s a good value for a 2-pack, but double-check your cap’s diameter and venting requirement first—especially on older or specialty models.
