Fairly priced and easy to install. ### ⭐⭐⭐⭐⭐ Worked great *by J***N on November 27, 2025* Worked great for my 08 harley. Was able to stop my fuel leak. Fit just right. Not to hard to do either. Good price if you can do it yourself. ### ⭐⭐⭐⭐⭐ 2,004 Heritage FLSTC I *by F***0 on April 10, 2026* I needed to pull the tank, and years of experience tells me when you have to pull your bike apart, that's the time to replace any relatively cheep parts that have a tendency to go bad. O-rings and gaskets are a perfect example of that. Your petcock has 2 O-rings and the line has 1. I would recommend buying this kit and an extra set of O-rings that include the small one for the line. I also recommend, when you install the new O-rings in the petcock, you install the lower (largest ring) first. This is so the deeper (inner most small ring) does not have to pass over the empty groove and risk barfing it up. So.... this lets it slip past the first groove with no risk of damage. A tiny bit of grease or oil helps the rings cooperate. ## Frequently Bought Together - MC-300 Fuel Tool Kit Replacement for Harley Davidson Tool Kit EFI Check Valve Rebuild Kit compatible with Harley Davidson 2001-2022 - Fuel-Tool Check Valve Repair Tools MC-400 - mc700 Fuel Line Rebuild Kit fits for HARLEY --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/607463272-mc-300-fuel-check-valve-rebuild-kit-for-harley-davidson](https://www.desertcart.sg/products/607463272-mc-300-fuel-check-valve-rebuild-kit-for-harley-davidson) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-27*
