The Range Rover Classic & Discovery 300Tdi Silicone Fuel Filler Hose to Tank (ESR2834) is a high-performance replacement manufactured from premium-grade fluorosilicone for superior resistance to fuels, oils, and vapours. Built to the same 300 mm length as the original component, this direct-fit hose connects the filler neck to the fuel tank with enhanced durability and long service life. Constructed with a fluorosilicone inner lining, reinforced with polyester braids, and finished with a high-quality silicone outer layer, the hose provides excellent chemical resistance while maintaining flexibility and structural integrity. Operating across temperatures from -50°C to +180°C (with peaks up to +250°C), it offers reliable performance in demanding automotive environments. Designed as a direct replacement for OE part ESR2834, this upgrade ensures a secure fit and long-lasting resilience in both on-road and off-road conditions.

The fluorosilicone inner lining ensures compatibility with diesel fuels, petrol, and associated vapours, preventing swelling or degradation common in rubber hoses. Reinforced with polyester braid, the hose maintains dimensional stability and resists cracking under continuous use. Its smooth bore supports efficient fuel flow with minimal restriction, while the outer silicone layer provides long-term resistance to heat, ozone, and environmental exposure. The 300 mm direct-fit length ensures simple installation as a replacement for OE part ESR2834, with improved reliability compared to factory rubber hoses.

Applications include direct replacement fuel filler connections on Range Rover Classic and Land Rover Discovery 300Tdi models. Suitable for both restoration projects and daily use, the silicone fluorosilicone filler hose upgrade ensures secure, fuel-resistant performance with long service life in rugged Land Rover environments.
