There is an upper one with the check valve. Typically the lower one needs replaced if the coupler is leaking. **Q: What size in millimetres is the lower o ring for the Harley check valve?** A: As someone who has tried to replace the o-rings both with and without this tool, i will recommend whenever possible to just replace the whole assembly, hose and all with the oem part. save yourself the hassle. **Q: where is the product made? thanks.** A: The tag and card inside have no info. Maybe if you go to fueltool.com you can find the answer. **Q: Will this fit a 2009 xl1200n** A: Only if its fuel injected! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Durable O-Rings *by M***D on April 13, 2026* Ordered this item to fix a small fuel leak.
