Warranty and refund

The manufacturer offers a one-year manufacturer’s warranty (12 months). The warranty applies only to the conversion kit, the included wiring harness, and their functionality.

The use of eFlexFuel conversion kit happens at the user’s own risk. Please take into account that a warranty offered by a car manufacturer may be void once a conversion kit has been connected to the car’s systems.

The manufacturer does not make up for damage caused to the car by the use of ethanol containing fuel or the use of eFlexFuel conversion kit. Neither does the manufacturer make up for damage caused by the installation to the product, the installation’s target or the person carrying out the installation, if the installation is carried out by the customer or by customer’s agent.

The manufacturer recommends replacing the fuel hoses and gaskets with ones that meet the SAE30R9 requirements and are therefore better capable of enduring ethanol exposure.
