594061 Fuel Tank Cap Compatible with Briggs & Stratton 675EXi 725EXi Engines, Lawn Mower Gas Cap Replacement for Toro Recycler, Craftsman M110 M220 M230, Replaces 84004416 597414

What It Is

This is a replacement fuel tank cap designed for Briggs & Stratton 675EXi and 725EXi engines, commonly found on Toro Recycler and Craftsman M110, M220, and M230 walk-behind mowers. It seals the fuel tank to prevent leaks and evaporation while allowing venting for proper fuel flow.

Fitment & Compatibility

Before buying, check these specifics:

• Engine family: Confirms to Briggs & Stratton 675EXi (model series 12A-xxx) and 725EXi (model series 12B-xxx). Cross-reference your engine model number (stamped on valve cover or blower housing).
• Mower models: Direct fit for Toro Recycler (models with Briggs EXi engines) and Craftsman M110, M220, M230. Not for other Craftsman or Toro models using different cap designs.
• OEM numbers: Replaces Briggs & Stratton 594061, 84004416, and 597414. If your cap has a different OEM number, measure the cap’s outer diameter (approx. 1.5 inches) and thread pitch. This cap uses a standard 1/4-turn bayonet-style lock, not a screw-on thread.
• Deck size: Irrelevant – cap fitment depends only on engine and fuel tank neck, not deck dimensions.

Key Things to Know

• Quality: Aftermarket cap, not OEM. Reviews are positive (5.0/5), but some users report slightly looser fit than OEM. Check for fuel odor after install.
• Installation: Tool-free – just align the tabs and twist 1/4 turn clockwise until it clicks. No gasket or sealant needed. If it wobbles, the tank neck may be warped.
• Common gotcha: This cap is vented. If your engine runs lean or stalls after replacement, the vent may be clogged – clean the tiny hole on top with a pin. Don’t use it on older non-vented tanks.
• No return if wrong: Aftermarket caps rarely list all compatible models. If it doesn’t fit, you’re out $8.79 unless the seller accepts returns.

Should You Buy It

Buy this if you have a Briggs & Stratton 675EXi or 725EXi engine and need a cheap, functional replacement for a lost, cracked, or leaking cap. It’s a solid budget option for common Craftsman and Toro mowers, but if you want an exact OEM fit, spend ~$15 for the genuine Briggs & Stratton 594061.
