Fuel Cap 2-1/4" Gas Cap fit for Club Car Carryall-294 XRT1500 for Ariens Mini-Zoom Sport-Zoom EZR HVZ for John Deere STX SRX for MT-D Riders 01538400 125-384 1015188 1027516-01

What It Is

This is a 2-1/4" diameter replacement fuel cap designed for gas tanks on Club Car Carryall-294, XRT1500, Ariens Mini-Zoom/Sport-Zoom/EZR/HVZ zero-turn mowers, John Deere STX/SRX lawn tractors, and MT-D riders. It replaces multiple OEM part numbers (01538400, 125-384, 1015188, 1027516-01) and is intended to seal the fuel tank to prevent spills and fumes.

Fitment & Compatibility

Before buying, check these three things:

• Cap diameter: Measure the inside diameter of your fuel tank neck. This cap fits a 2-1/4" (57mm) opening. If your cap is slightly smaller or larger, it won’t seal.
• Thread type: This is a threaded cap. Ensure your tank neck is threaded (not a push-on or bayonet style). Most compatible models listed above use standard right-hand threads.
• OEM cross-reference: Verify your original cap part number matches one of these: 01538400, 125-384, 1015188, or 1027516-01. If your cap looks different (e.g., has a vent hole or tether), this cap may not include those features—confirm your tank requires a non-vented cap.

Key Things to Know

• Quality: At $6.89, this is a budget-friendly replacement. Most buyers report it fits snugly and stops leaks, but a few note the plastic feels slightly thinner than OEM. It should last a season or two under normal use.
• Installation: No tools needed. Simply unscrew the old cap and screw on the new one. Tighten by hand only—overtightening can crack the plastic.
• Common gotcha: Some users mention the cap doesn’t include a tether or strap. If your original cap was tethered, you’ll need to secure this one separately to avoid losing it.
• Venting: This cap appears to be non-vented. If your mower’s gas tank relies on a vented cap (common on older models), this may cause vapor lock or pressure buildup. Check your tank’s venting system before buying.

Should You Buy It

If you need a simple, low-cost replacement for a 2-1/4" threaded fuel cap on a Club Car, Ariens, John Deere, or MT-D rider, and your original cap was non-vented and not tethered, this is a solid buy. Skip it if you require a vented cap, a tether, or a more durable metal construction for heavy commercial use.
