Flex fuel hoses

Flex fuel hoses are used in fuel systems where higher demands are placed on materials, sealing and durability than with regular petrol use. When a car runs on ethanol blends, E85 or as part of an ethanol-compatible fuel system, it is important to choose fuel hoses that are suitable for ethanol-containing fuel, as ordinary rubber hoses can become hard, porous or break down over time. E85 fuel hoses are therefore an obvious choice for tuning, motorsport and custom-built cars where reliability and correct fuel supply are essential.

At Qualitec, you will find ethanol-resistant fuel hoses for use in modern fuel systems where a safe solution is required for both petrol and ethanol-containing fuel. They are often used together with AN fittings, fuel pumps, catch tanks, fuel rails, filters and flex fuel sensors, and they are suitable for both road cars with upgraded fuel systems and more demanding motorsport projects. A correctly selected fuel hose for E85 makes it easier to build a fuel system that can withstand high load, high flow and the chemical effects that ethanol can cause.

Flex fuel hoses are especially relevant when building or upgrading fuel systems where improved compatibility with E85, higher safety and longer service life throughout the system are desired. They are often used in conversions where standard fuel hoses are no longer sufficient, or where a more professional solution with focus on performance and durability is required. Whether you are building for trackday, motorsport, road car or a custom project, it is important to choose the correct fuel hoses for the purpose.
