⚠️ 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.

The kit can be supplied for the 0280150014 / 0280150023 injectors and the ferrules will be exchanged for additional hose clips — please add a note at checkout if you require the kit for the 0280150014 / 0280150023.
