Royal Enfield 1020017/A – Quick Connector (Fuel Hose / Injector Line Quick Coupler) for Bullet 500 Euro 4 (B5) & Classic 500 Euro 4 (C5) | Genuine OEM

Royal Enfield 1020017/A is the genuine OEM Quick Connector used in the fuel tank / fuel hose-to-injection line connection on Euro-4 UCE 500 EFI models. It is listed as “QUICK CONNECTOR” in Royal Enfield parts catalogs and appears in the Fuel Tank parts list for Bullet 500 Euro IV, positioned alongside related injection hardware (e.g., injector cap and the fuel hose/PA tube line items).

This connector is typically replaced when the original coupling becomes loose, cracked, leaking, or damaged during fuel tank removal, or when the locking tabs wear out and the line no longer seats securely. Using an OEM quick connector is strongly recommended over generic couplers because fuel-line sealing and locking tolerances are critical for safety, leak prevention, and correct fitment with the factory hose/pipe ends. 

Fitment is kept zero-guesswork: Hitchcocks lists this as a Quick Connector for Euro-4 B5/C5 models, and the Bullet 500 Euro IV catalog confirms the exact part number 1020017/A under the fuel tank group.

FAQs 

1. What is Royal Enfield 1020017/A used for?
   It is the OEM Quick Connector used in the fuel tank / fuel hose-to-injection line connection on Euro-4 UCE 500 EFI models. 

2. Which bikes are confirmed for 1020017/A?
   Confirmed for Euro-4 B5/C5 family (Bullet 500 EFI Euro-4 and Classic 500 EFI Euro-4). 

3. My bike smells like petrol / has wetness near the fuel line joint—will this fix it?
   If the leak is from a worn/damaged quick connector or locking mechanism, replacement can fix it. If the issue is from a hose crack, O-ring/seal, or improper seating, you must diagnose and replace the correct component. Fuel leaks are safety-critical—repair immediately. 

4. Is this the same as a “fuel pump connector”?
   This is catalogued as a Quick Connector and shown in the Fuel Tank group near injection line items. It’s commonly used as the quick-coupling in the fuel line system, but you should match your microfiche diagram to confirm the exact location on your variant. 

5. How do I verify fitment before ordering to avoid a wrong part?
   Check your bike is Bullet 500 / Classic 500 Euro-4 (BS4) and confirm the connector in your parts diagram is 1020017/A. If your diagram shows a different number, do not order this one
