594061 Lawn Mower Gas Fuel Tank Cap Compatible with B & S 675EXi 725EXi Engine Toro Craftsman Gas cap Replacement(2 Pack)

What It Is

This is a 2-pack of replacement gas fuel tank caps designed for Briggs & Stratton 675EXi and 725EXi engines, commonly found on Toro and Craftsman walk-behind mowers. It seals the fuel tank to prevent leaks and evaporation.

Fitment & Compatibility

Before buying, verify your engine model number (e.g., 12A-xxx-xxx for Briggs & Stratton). This cap fits 675EXi and 725EXi engines only—not older series like 500e or 850. Check your mower’s deck size doesn’t matter; focus on the tank opening diameter (~1.5 inches) and cap thread type (standard 1/4-turn). OEM part number 594061 is the direct match. If your original cap has a breather hole or tether, this replacement may lack both—confirm your tank requires a vented cap.

Key Things to Buy

• Quality: User reviews average 3.7/5; some report caps fit loosely or don’t seal tightly, leading to fuel smell or leaks. Inspect the gasket before installation.
• Installation: Tool-free—just twist on. Ensure it’s fully seated and clicks into place. Overtightening can crack the cap.
• Gotchas: Not all aftermarket caps fit perfectly. If your mower has a fuel tank with a recessed neck, this cap may sit flush and be hard to grip. The 2-pack is useful if you lose caps often, but single OEM caps may offer better seal consistency.
• Venting: If your engine requires a vented cap (common on older models), this cap is likely non-vented. Check your owner’s manual or test by running the mower—if it stalls after a few minutes, you need a vented cap.

Should You Buy It

This is a budget-friendly stopgap for losing or cracking a cap on a 675EXi or 725EXi mower, but if you need a reliable seal or a vented cap, spend a few dollars more on the genuine Briggs & Stratton part.
