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 ### ⭐⭐⭐⭐⭐ This is the one to buy for lower fuel oring *by A***R on February 2, 2026* This is the one you need, dont waste your money on others, like I did. (2016 ultra limited) Im not sure how others had positive reviews, they aren't even close. ### ⭐⭐⭐⭐⭐ good to have on hand *by M***N on February 18, 2026* did the trick ### ⭐⭐⭐⭐⭐ Worked exactly as expected! *by A***R on February 8, 2020* I was a bit worried about buying these o-rings based on some of the reviews. But I decided to go for it and give it a try. I had to use a dental pick to get the old o-ring out, and when I did, it came out in fragments. It was dried out and completely disintegrated when I removed it. I have a 2007 883XL Sportster and the new o-rings looked too small at first, but I figured I should at least try them since I had nothing to loose... I decided to lubricate the o-ring with some silicone lube I use for the o-rings in my swimming pool before installing. I am sure that a professional will tell me that is the wrong lubricant to use, but we are talking about such a small o-ring and a small surface area I figured it is probably ok. The new o-ring was a bit tricky to get into it's seat, but I was able to use a socket that fit perfectly into the check valve and that pushed the o-ring right into its seat without twisting it. I think this was also simplified because I didn't try to insert the o-ring dry. - I reconnected the fuel line, put the key in the ignition and flipped the switch to 'RUN' which pressurizes the fuel pump/line. Previously this would have _sprayed_ gasoline all over the place, but the new o-ring did the trick. Not a drop of fuel leaking from the check valve. I took the bike around the block a few times, and the assembly remained dry as a bone. So I have to give the product a good review. It worked as advertised and I really only needed 1 o-ring. So I have a pack of 4 spares to throw on the bench for the future. ## Frequently Bought Together - Fuel Tool EFI Check Valve Lower O-Ring - MC200-5 - Fuel Tool MC600-5 Replacement Male End O-Ring - Fuel-Tool Check Valve Repair Tools MC-400 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/33375220-fuel-tool-efi-check-valve-lower-o-ring-mc200-5](https://www.desertcart.pl/products/33375220-fuel-tool-efi-check-valve-lower-o-ring-mc200-5) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-02*
