Lawn Mower Gas Cap 594061 Gas Cap Compatible with B&S 675EXi 725EXi Engine Toro Craftsman Lawn Mower Replacement Gas Tank Cap - Replace 594061 - Pack of 1 Review

Overview

This isn’t a mower — it’s a replacement gas cap for specific Briggs & Stratton engines, primarily the 675EXi and 725EXi series, found in Toro, Craftsman, and other popular walk-behind mowers. If your original cap is cracked, leaking, or lost, this $7.59 part is designed to get you back to mowing. It’s a simple, direct-fit swap for the 594061 part number, and it’s best for anyone who owns a mower with those engines and needs a quick, affordable fix.

Who Should Buy This

• Homeowners with a dead or leaky cap: If your current gas cap is cracked, won’t seal, or is letting fuel evaporate, this is your exact fix. No need to replace the whole mower or call a repair shop.
• DIY lawn equipment owners: You know your mower’s engine model (check the sticker near the spark plug or under the air filter). You’re comfortable with a simple twist-on replacement and want to avoid dealer markup.
• Owners of Toro, Craftsman, or other mowers with B&S 675EXi/725EXi engines: This cap is specifically designed for those engines. If you have a different engine series, this won’t fit.
• Budget-conscious buyers: At $7.59, this is cheaper than most OEM caps from a dealer. If you just need a functional seal and don’t care about brand-name packaging, this saves you a few bucks.

Key Features Breakdown

• Compatibility: Fits B&S 675EXi and 725EXi engines. That’s a huge range of Toro, Craftsman, John Deere, and Snapper mowers from the last 10-15 years. Check your engine model before buying, but it’s a common fit.
• Part Number 594061: This is the OEM reference number. If your old cap has “594061” stamped on it, this is a direct replacement. No adapters, no modifications needed.
• Pack of 1: Simple, single cap. No extras, no gimmicks. You get exactly what you need.
• Material: Standard plastic gas cap with a rubber gasket. It’s not heavy-duty metal, but it’s built to the same specs as the original. The gasket creates a vapor-tight seal to prevent fuel evaporation and spills.
• Price: $7.59. That’s about half what you’d pay at a local small-engine shop or dealer. For a basic part, it’s a fair deal.

Pros

1. Exact fit for common engines: This cap screws on smoothly and seals tight on B&S 675EXi and 725EXi engines. No wobble, no cross-threading.
2. Solves fuel evaporation issues: If your old cap had a cracked gasket, you were losing gas through evaporation. This cap seals properly, saving you fuel and reducing fumes.
3. Simple DIY install: No tools, no instructions needed. Just unscrew the old cap, screw on the new one. Takes 10 seconds.
4. Cheaper than dealer parts: OEM caps from a Briggs & Stratton dealer can run $12-$15. This is a direct alternative at a lower price.
5. Lightweight and easy to store: It’s a small plastic cap. Toss it in your shed or garage, and it won’t take up any space.
6. Works with ethanol-blended fuels: The rubber gasket is compatible with E10 and E15 gasoline, which is common at most pumps. No swelling or cracking from modern fuel.

Cons

1. Low average rating (3.2/5 stars): With only 4 reviews, it’s hard to gauge long-term reliability. Some users report the gasket doesn’t seal perfectly after a few months. It’s a gamble.
2. Plastic construction: The cap is all plastic. If you drop it on concrete or overtighten it, the threads can crack. A metal cap would be more durable, but this is standard for the price.
3. Not universal: If you have a different engine (like a B&S 500EXi or a Honda engine), this cap won’t fit. You must verify your engine model.
4. No venting mechanism: Some original caps have a small vent to equalize pressure in the tank. This cap doesn’t appear to have a dedicated vent, which could cause a vacuum lock over time, especially in hot weather. If your mower stalls after running for a while, this might be the issue.

Bottom Line

If your current gas cap is broken or leaking, this replacement is a solid, affordable fix for Toro, Craftsman, and other mowers with B&S 675EXi or 725EXi engines. It’s cheap, easy to install, and does the basic job of sealing your fuel tank. But it’s not perfect — the plastic is a bit fragile, and the lack of a vent could be a problem for some users. For $7.59, it’s worth a try, especially if you’re handy and can return it if it doesn’t fit. I recommend it for quick, budget-friendly repairs, but if you want a more durable cap with a vent, consider spending a few dollars more on an OEM part from a dealer.

Frequently Asked Questions

Q: Will this cap fit my Toro Recycler with a B&S 675EXi engine? A: Yes, almost certainly. The 675EXi engine uses the 594061 cap. Just double-check your engine model number (look for a sticker on the engine shroud or near the spark plug). If it says “675EXi” or “725EXi,” you’re good.

Q: My old cap had a small hole or vent. Does this cap have one? A: This cap does not have a visible vent hole. It relies on the seal being slightly imperfect to allow pressure equalization. If your mower stalls or runs rough after 10-15 minutes, try loosening the cap slightly. If that fixes it, you may need a vented cap.

Q: Can I use this cap with ethanol-free gasoline? A: Yes, it’s compatible with ethanol-free gas, regular E10, and even E15. The rubber gasket is designed to handle ethanol blends without degrading. Just avoid E85.
