Holley E85 Fuel Tester

Calibrating the right air/fuel mixture is important to gain proper power and efficiency from your carburetor and engine. But for vehicles running E85 fuel#, proper calibration is difficult if you don't know the exact percentage of ethanol-to-gasoline in the fuel.
Because E85 fuel can vary in the amount of ethanol and gasoline mixture#, Holley's E85 Checker is an essential tool that can instantly determine the ratio in the E85 fuel you're using. Holley's E85 Checker fits in your pocket or tool box#, and is easy to use. Simply 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.
With the added benefits of 105 octane#, cooler engine temperatures and improved emissions#, Holley's E85 Checker can make a winning combination with any of Holley's E85 calibrated Carburetors and fuel-pumps for your vehicle.
