These parts should fit your unit. Lindsay GPS **Q: My model number is 4kyfa 6747P, does this work with mine?** A: I have same model # but mine has EVAP. Will it work cause it says specifically Non-Evap ? **Q: My model number is 4ky fa26100j, is this the same as a ky4000?** A: Yes, this kit will fit your generator. **Q: My model is 4kyfa26100p. Will this work?** A: I purchased the tune up kit for my 4KW Oman Generator, but I do not know about your particular Oman model. I would look up on Google your Oman model, and cross reference the part numbers. You can not get a better price then on Amazon. I know the Amazon parts are certified Oman Parts. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product. *by K***E on 23 June 2026* Great product, came with everything. Worked great ### ⭐⭐⭐⭐⭐ Fast shipping and good quality *by E***D on 27 April 2024* Good kit ### ⭐⭐⭐⭐⭐ Exactly what was needed. A complete kit *by T***T on 22 September 2024* Needed to service my Onan 4000 and no one locally had the parts or a service kit. Amazon it is! This is exactly what you’ll need to service your ONAN 4000 generator. My fuel filter is located underneath the unit and requires me to remove the generator from the trailer in order to access the fuel filter. This is not feasible, so I didn’t replace the fuel filter. This kit is exactly what is required for a complete service. ## Frequently Bought Together - GPS GENERATOR PARTS SPECIALIST Tune Up Kit for Onan RV Generator Model KY 4000, Spec A-R - Camco TastePURE RV Water Filter - New & Advanced RV Inline Water Filter with Flexible Hose Protector - GAC & KDF Water Filter - Made in USA - Camping Essentials for Fresh Drinking Water (40043) - RVGUARD RV Water Pressure Regulator Valve, Brass Lead-Free Adjustable Water Pressure Reducer with Gauge and Inlet Screen Filter for RV Camper Travel Trailer --- ## 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.jp/products/222412020-gps-generator-parts-specialist-tune-up-kit-for-onan-rv](https://www.desertcart.jp/products/222412020-gps-generator-parts-specialist-tune-up-kit-for-onan-rv) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-22*
