Royal Enfield Petrol Tank Bullet Classic BS4 Blue
Looking for an authentic replacement Royal Enfield Petrol Tank Bullet Classic BS4 Blue? Featuring the original 13.5 litres fuel tank capacity, this heavy-duty replacement fuel tank is crafted from deep-drawn Cold Rolled Coil (CRC) sheet steel, engineered specifically for the Royal Enfield Classic 350 BS4 (Carburettor UCE platform with EVAP emission port). Built strictly to original factory blueprints, it delivers an exact bolt-on fit to your motorcycle frame without requiring custom brackets, welding, or chassis alterations.
Whether you are replacing an original tank plagued by internal rust flake contamination, dented side panels from road debris, or seam weeping around the fuel bung, this tank restores showroom fresh styling and reliable fuel delivery. The deep blue finish is sealed under multiple coats of automotive-grade polyurethane clear lacquer, providing long-term protection against UV sunlight, rain showers, and petrol drips during fill-ups.

Installation & Maintenance Tips
To ensure maximum lifespan from your new fuel tank, follow these straightforward workshop best practices before hitting the road:
- Pre-Installation Flush: Always rinse the interior of the new tank with half a litre of fresh petrol before bolting it down. This clears any transit packaging dust and ensures clean fuel flows to your fuel filter or carburettor jets.
- Rubber Dampers: Inspect your front frame rubber pucks and rear mount isolators. If your motorcycle has high mileage, replacing hardened rubbers prevents engine vibration transfer to the fuel tank seams.
- Seals & Gaskets: When transferring your fuel tap or pump module, install a fresh fuel-resistant Viton washer or O-ring and apply a thread sealant paste to guarantee a drip-free union.
- Paint Care: After mounting, treat the blue paint with a coat of high-grade carnauba paste wax or ceramic detailer to create a protective barrier against road grime and petrol staining.
