594061 Fuel Tank Cap Gas Cap Compatible with for Lawn Mower for B& S w/Tether 675Exi 725Exi Series

What It Is

This is a replacement fuel tank cap with a tether for Briggs & Stratton engines, specifically the 675Exi and 725Exi series. It prevents fuel spillage and evaporation while keeping the cap attached to the tank.

Fitment & Compatibility

• Direct fit for: Briggs & Stratton 675Exi and 725Exi series engines (common on push mowers, riders, and pressure washers).
• OEM equivalent: Cross-references with Briggs & Stratton part 594061 (verify your engine’s parts list).
• Check before buying: Measure your tank opening diameter (approx. 1.5 inches) and confirm the tether length matches your tank neck. Not universal—will not fit non-Briggs engines or older 500/600 series without Exi.
• Deck size irrelevant: Works on any machine with the compatible engine, regardless of deck width.

Key Things to Know

• Quality concern: 2.9/5 rating with only 3 reviews suggests inconsistent sealing or brittle plastic. Expect possible leaks if cap is cross-threaded.
• Installation: Simple—remove old cap, screw on new one hand-tight only. Over-tightening can crack the cap or strip the threads.
• Tether durability: Tether is thin plastic; may snap if caught on debris or during transport. Not a heavy-duty design.
• Fuel compatibility: Works with regular gasoline, but ethanol blends may degrade the gasket over time. Check for swelling after a few months.

Should You Buy It

Only if you need a cheap, quick fix for a lost or broken cap on a Briggs 675Exi/725Exi engine and don’t mind replacing it again in a season or two. For long-term reliability, spend a few dollars more on an OEM Briggs cap.
