2pcs 2" ID Fuel Cap for Murray 92317MA, Briggs 795027, MTD 751-3111...More

What It Is

This is a set of two 2-inch inner diameter (ID) fuel caps designed to replace worn or missing caps on push mowers, riding mowers, and small engines. They fit Murray, Briggs & Stratton, and MTD fuel tanks that use a 2" ID neck.

Fitment & Compatibility

• Measure first: The critical spec is the inner diameter of the fuel tank neck—must be exactly 2 inches. The cap’s outer diameter is roughly 2.5 inches, so verify your tank opening matches.
• OEM cross-reference: Directly replaces Murray 92317MA, Briggs & Stratton 795027, and MTD 751-3111. Also fits many Craftsman, Troy-Bilt, and Cub Cadet models using the same tank.
• Not universal: Does not fit 1.5" or 2.5" ID necks. Check your engine brand and model number online or on the old cap. If your cap has a different part number, measure before buying.
• Aftermarket part: Not genuine OEM, but rated for the same fit. Expect slight variation in plastic color or vent design.

Key Things to Know

• Vented design: These caps have a small vent hole to prevent vacuum lock in the tank. If your mower stalls or runs rough after fueling, the vent may be clogged—clean with a pin.
• Easy install: No tools required—just twist off the old cap and twist on the new one. Takes 30 seconds per cap.
• Quality note: At $9.90 for two, these are budget-friendly. Some users report the plastic feels thinner than OEM, but they hold fuel without leaks if seated properly.
• Common gotcha: If the cap feels loose or cross-threads, check that the tank neck is clean and undamaged. A cracked neck will need a new tank, not just a cap.

Should You Buy It

Buy this if you have a 2" ID fuel tank on a Murray, Briggs, or MTD engine and need a functional, low-cost replacement. It’s a solid value for two caps—keep one as a spare. Avoid if you need an exact OEM match for a warranty or if your tank neck is damaged.
