Lawn Mower gas Fuel Tank Cap for B & S 675EXi 725EXi Series 875 Professional Series Engines Craftsman m230 m110 Toro Replacement 594061

What It Is

This is a replacement gas fuel tank cap designed for Briggs & Stratton 675EXi, 725EXi, and 875 Professional Series engines, commonly found on Craftsman m230 and m110 walk-behind mowers, as well as some Toro models. It replaces OEM part 594061 and simply seals the fuel tank to prevent leaks and debris entry.

Fitment & Compatibility

Before buying, confirm your engine model number (e.g., 675EXi, 725EXi, 875 Professional) – it’s stamped on the engine shroud or under the air filter cover. This cap fits Craftsman m230 and m110 mowers specifically, but also works on select Toro models with the same engine series. Check the cap’s outer diameter (typically ~1.5 inches) and thread pattern (standard right-hand twist). This is an aftermarket replacement, not OEM Briggs & Stratton, so fitment may vary slightly on older or non-listed models. Verify your original cap part number matches 594061 or 792039.

Key Things to Know

• Quality concerns: With a 3.6/5 rating from only 8 reviews, some users report a looser fit or less durable plastic than OEM. Inspect the seal/gasket carefully before installation.
• Easy installation: No tools required – just unscrew the old cap and twist on the new one. Hand-tighten only to avoid cross-threading.
• Common gotcha: If your mower has a tethered cap (attached to the tank by a plastic strap), this replacement may not include one. You’ll need to reuse the old tether or buy separately.
• Gas smell check: After installing, run the mower briefly and check for fuel odor around the cap – a poor seal can cause vapor leaks or spills on slopes.

Should You Buy It

This cap is a budget-friendly fix if your original is cracked, lost, or leaking and you’re okay with an aftermarket part. It’s right for DIY owners of Craftsman m230/m110 or Toro mowers with B&S EXi/Professional engines who need a quick, low-cost replacement. Skip it if you want OEM fitment precision or a tethered cap – spend a few dollars more for the genuine Briggs & Stratton part.
