GENUINE OEM HONDA (HRX217KHMA) (HRX217KHXA) (HRX217KTDA) (HRX217KVKA) (HRX2172HMA) (HRX2172HXA) (HRX2172VKA) Walk-Behind Lawn Mower Engines Fuel Tank GAS CAP

What It Is

This is a genuine OEM Honda fuel tank cap designed for select Honda HRX217 walk-behind mower models. It seals the fuel tank to prevent leaks, spills, and debris entry while maintaining proper venting for smooth engine operation.

Fitment & Compatibility

Before buying, confirm your mower’s exact model number—not just the series. This cap fits: HRX217KHMA, HRX217KHXA, HRX217KTDA, HRX217KVKA, HRX2172HMA, HRX2172HXA, and HRX2172VKA. It does not fit older HRX217 models (e.g., HRX217HXA without “2” in the suffix) or other Honda mower series (e.g., HRR, HRS). Check the cap’s thread size (approx. 39mm outer diameter) and compare with your current cap. If your cap is missing or cracked, measure the tank opening to ensure match. OEM part number is 17620-Z0L-801.

Key Things to Know

• Quality: Genuine Honda part—matches original fit, seal, and venting. Aftermarket caps may leak or cause fuel starvation due to poor venting.
• Installation: Simple twist-on/off; no tools required. Takes 30 seconds.
• Common Gotcha: If your mower runs rough or stalls after replacing the cap, the vent may be blocked. Test by loosening the cap slightly—if engine improves, the cap is defective or incompatible.
• Price Note: At $28.95, it’s pricier than generic caps, but it lasts years and avoids fuel system issues.

Should You Buy It

If you own one of the listed HRX217 models and need a reliable, leak-free replacement, this OEM cap is the right choice. It’s a direct fit with no guesswork, and the verified venting prevents fuel delivery problems that cheap alternatives can cause. Skip it if you have a different Honda mower model or want a sub-$10 option (but expect lower quality).
