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
· Temperature range: -40°C to +125°C (up to +150°C for short periods)
· Meets multiple international standards: DIN 73379-B1, SAE J30R9, BMW GS 93010, DBL 6256.70, GME 08 007, VW TL 524 24 — providing superior resistance to degradation and fuel permeation compared to standard hoses
Sold Per 0.5 Metre
This hose is sold in lengths of 0.5 metre. If you require 1 metre, increase the quantity to 2, and so on.

⚠️ Petrol Compatibility & Injector Handling Notice
Petrol Only: Strictly for petrol engines, not diesel. Check compatibility before buying.
Delicate Mechanisms: Injectors—especially historic hose injectors—are fragile. Some components cannot be removed, replaced, or obtained anywhere. Check our kits before dismantling your own parts; some items are not available aftermarket. Do not force components loose or strip your injectors down until you know what we can replace, or the injector may need replacing.
Expert Fitment Advised: We strongly advise using a competent professional for installation to avoid common issues like over-tightening hose clamps or damaging pintle needles. If you are unsure about dismantling, fitting or refitting an injector, seek advice from a competent professional before proceeding.
Lubrication: The only lubricant we recommend is a light smear of clean engine oil, wiped almost completely off before fitting.
