Mower Fuel Tank Gas Cap 7012515YP 2681S 3081 Fits Snapper Rear Engine Rider ZTR

What It Is

This is a replacement fuel tank gas cap designed for Snapper rear-engine riders and ZTR mowers. It seals the fuel tank to prevent leaks, evaporation, and debris entry, and includes a built-in vent to maintain proper fuel flow.

Fitment & Compatibility

Before buying, verify these specifics:

• OEM part numbers: Cross-reference with 7012515YP, 2681S, and 3081. This cap fits many Snapper models, including RE, RER, and ZTR series from the 1990s through early 2000s.
• Thread size & type: Cap uses standard 2-inch (50mm) coarse threads. Measure your tank opening diameter—if it’s smaller or larger, this won’t fit.
• Deck size: Not relevant; this cap fits any deck size as long as the tank opening matches.
• Vent style: This is a non-pressure vented cap. If your original cap had a separate vent line or a pressure-release valve, this may not be compatible.
• Aftermarket vs. OEM: This is an OEM-spec replacement, not a universal cap. Avoid universal caps unless they match the thread pitch and vent design exactly.

Check before buying: Remove your old cap and compare the thread pattern, outer diameter, and vent hole location. If your cap has a separate rubber gasket, ensure this cap includes one (it does). If your tank neck is cracked or warped, a new cap won’t seal.

Key Things to Know

• Quality: Made from durable plastic with a rubber gasket. The vent is integrated and rarely clogs, but check it if the mower runs lean or stalls.
• Installation: Tool-free; simply screw on hand-tight. Do not overtighten—it can crack the tank neck. Replace if the gasket is hard, cracked, or missing.
• Common gotchas: The vent can get blocked by debris (dust, grass clippings). If the engine sputters or dies after running a few minutes, clean the vent with compressed air. Also, this cap may not fit newer Snapper models with EPA-mandated vapor-recovery systems.
• Price vs. value: At ~$13, it’s competitively priced. Cheaper universal caps often leak or don’t vent properly, leading to fuel starvation.

Should You Buy It

Buy this if you have a Snapper rear-engine rider or ZTR from the 1990s–2000s with a standard 2-inch threaded tank opening and need a direct, vented replacement. Avoid it if your mower uses a different thread size, a pressure-style cap, or a separate vent line—those require a different part.
