The warranty covers the free change or repair of the product in case of defects or any other manufacturing problem under normal conditions of use and under the manufacturer’s recommendation.

The warranty is restricted to the product operation and does not apply to the possible" vehicle poor performance” after its installation due to other vehicle maintenance issues. Fullflex International in no way covers nor holds the responsibility of guarantee with the use of Ethanol in any vehicle that this product is installed. We do although recommend that users of Fullflex do obtain an outside warranty company that can warranty any possible damage related to high mileage, poor drivability or the use of E85 or Ethanol. This is an aftermarket conversion unit that the buyer or user holds responsibility of the installation. We place no claims with the improvement of fuel mileage or engine life due to the use of Ethanol and Fullflex.

* Note: It is always important to make sure your vehicle is in top operating condition before installing our system.
