594061 Fuel Tank Cap Fit for Briggs & Stratton 675EXi 725EXi Compatible with Craftsman M110 M220 M230 Toro 21465 Lawn Mower Replaces 84004416 597414 799585 Gas Tank Cap

What It Is

This is an aftermarket fuel tank cap designed to replace the original cap on Briggs & Stratton 675EXi and 725EXi engines. It fits specific Craftsman M110, M220, M230, and Toro 21465 lawn mowers, serving as a direct replacement for OEM caps 84004416, 597414, and 799585.

Fitment & Compatibility

Before buying, check these three things:

1. Engine model – Works only with Briggs & Stratton 675EXi and 725EXi engines. Look for the model number on the engine shroud or valve cover.
2. Mower model – Confirmed for Craftsman M110, M220, M230, and Toro 21465. Not guaranteed for other models even if they share the same engine.
3. OEM cross-reference – Replaces 84004416, 597414, and 799585. If your current cap has a different OEM number, it likely won’t fit.
4. Physical dimensions – No specs listed. Expect a standard twist-on plastic cap with a ~1.5-inch diameter neck. Measure your tank opening if possible.

Note: This is an aftermarket part, not genuine Briggs & Stratton. Quality and seal may vary.

Key Things to Know

• Low rating (3.0/5) – Only 2 reviews, so take with a grain of salt. Buy from a seller with easy returns.
• Installation is trivial – Unscrew old cap, screw on new one. No tools needed.
• Common gotcha – The cap may not vent correctly on all tanks. If your mower stalls or leaks, check the cap seal and vent hole.
• Price is low ($7.58) – Cheap enough to try, but don’t expect OEM fit/finish.

Should You Buy It

Buy this if you need a budget replacement for a lost or broken cap on a Briggs 675EXi/725EXi engine and your mower is one of the listed models. Skip it if you want OEM quality, need a vented cap for a specific tank, or have a different engine – the low price isn’t worth risking a fuel leak or poor seal.
