Lawn Mower Gas Cap, 594061 Fuel Tank Cap & 593260 Air Filter Replacement for 725EXi 675EXi Series Engine

What It Is

This combo replaces the fuel tank cap (594061) and air filter (593260) for Briggs & Stratton 725EXi and 675EXi series engines, commonly found on walk-behind mowers, pressure washers, and generators.

Fitment & Compatibility

• Engine series only: Fits Briggs & Stratton 725EXi and 675EXi engines. Will not fit other series (e.g., 500E, 550EX, 850EX) without checking part numbers.
• OEM cross-reference: 594061 cap replaces OEM 594061, 698369, 795969. 593260 filter replaces OEM 593260, 5045H, 5090K. Compare your old part numbers.
• Measurements: Cap has a 1.5-inch thread diameter and 0.75-inch height. Filter is 3.5 x 2.5 x 1.5 inches. Confirm dimensions if your mower has a non-standard housing.
• Check your model number: Look for a stamped plate on the engine shroud or mower deck. Common models: 11A-020, 12A-829, 13A-325 (but verify engine series, not just mower brand).

Key Things to Know

• Quality: Aftermarket, not OEM. User reviews (4.7/5) indicate good seal and fit, but plastic may be slightly less durable than OEM.
• Installation: Both are tool-free, snap-on or screw-on replacements. Takes 2 minutes total. No gasket needed for the cap.
• Gotcha: The air filter is foam, not paper. Clean it with soapy water every 25 hours, replace annually. Do not oil it unless specified.
• Common issue: If the cap doesn’t vent properly, the engine may stall after running. Test by loosening the cap slightly—if it runs better, the cap is faulty.

Should You Buy It

Yes, if you need a budget-friendly, quick fix for a 725EXi or 675EXi engine mower with a loose cap or clogged filter. It’s a solid value for the price, but check your exact part numbers first—if you have a different engine series, this won’t fit.
