High Pressure Fuel Injector Hose German-Made Ethanol-Resistant 9.3mm ID x 15.3mm OD x 0.5 Metre

German-Manufactured Aramid-Braided Fuel Hose — 9.3mm ID, Sold Per 0.5 Metre

The same hose used in aerospace and aviation applications. This German-manufactured aramid-braided fuel hose is the only correct replacement for polyester-reinforced hoses on classic and modern fuel-injected engines. 100% ethanol-resistant and fully compatible with E10, bio-diesel (RME), and all commercially available fuels. This size is used for feed and return pipework.

⚠️ Why You Must Replace Your Old Fuel Hoses Now

UK fuel now contains up to 10% ethanol. Older polyester-reinforced hoses are not ethanol-resistant — they degrade from the inside out, becoming brittle and prone to cracking. A leaking fuel hose near a hot engine is a fire risk.

Don’t just replace the injector hoses — check and replace all hoses from the tank to the feed and return lines.

Construction

Multi-layer design engineered for high-pressure fuel systems:

· FPM (fluoro elastomer) rubber inner tube — chemical resistance and high-temperature performance

· ECO (epichlorohydrin) rubber intermediate layer — oil resistance and heat stability

· Braided aramid fibre reinforcement — exceptional tensile strength, pressure resistance and flexibility

· ECO rubber outer cover — resistance to weathering, ozone and oils

Technical Specifications

· Internal diameter: 9.3mm | External diameter: 15.3mm

· Working pressure: 10 bar | Bursting pressure: 50 bar | Testing pressure: 20 bar

· Minimum bending radius: 70mm
