Why Upgrade Your
Fuel Lines?
Modern E10/E85 fuels in Europe destroy factory rubber hoses from the inside out, causing dangerous leaks and fuel starvation.
Ethanol Degradation
Rubber hoses swell and crack under E10/E85 exposure. Our PTFE inner core is 100% immune to harsh racing fuels and ethanol.
Fuel Vapor & Mystery Leaks
Micro-cracks in aging lines cause fuel smell in your garage. PTFE offers zero vapor permeation, completely sealing your system.
Vapor Lock Near Exhausts
The stainless steel/nylon outer braid combined with PTFE withstands up to 230°C, ensuring safe routing near hot headers.
