Holley 26-147 E85 Fuel Tester

The simple process of calibrating the right air/fuel mixture is important to gain proper power and efficiency from your carburetor and engine.  For vehicles running E85 fuel, proper calibration is difficult if you don't know the exact percentage of ethanol-to-gasoline in the fuel.

E85 fuel can vary in the amount of ethanol and gasoline mixture, therefore, Holley's E85 fuel checker is the perfect tool to have on hand that can instantly determine the ratio in the E85 fuel you're using. Holley's E85 Checker is small and can fit in your pocket or tool box, and is easy to use. All you have to do is add water to the first line on the E-Checker and then pour in the E85 sample to the second line. Once the water is absorbed, the Holley E85 Checker will indicate the amount of ethanol in the fuel.
