WARNING: EDELBROCK CARBURETORS ARE NOT CALIBRATED FOR OR COMPATIBLE WITH ALCOHOL RACE FUEL OR E85
PUMP FUEL. USE OF ALCOHOL OR E85 IN YOUR EDELBROCK CARBURETOR WILL DAMAGE YOUR CARBURETOR AND VOID
ALL MANUFACTURE'S WARRANTIES. THESE FUELS CAN ALSO DAMAGE OTHER FUEL SYSTEM COMPONENTS, UNLESS
• Blended Fuels - Typically, two types of blended fuels are available: E10 and E15. E10 is a blend of fuel which contains no more than
10% ethanol, while E15 contains no more than 15% ethanol. As long as there is no more than 10% ethanol mixed with the gasoline,
your carburetor will function properly. As the percentage of ethanol climbs above 10%, a richer calibration may be required. Also,
because ethanol is more volatile than gasoline, hard hot starting and poor hot weather driveability may result.
Other blended fuels may contain either methanol or alcohol blended with gasoline. Methanol blended fuel should not be used in your
Edelbrock Performer or Thunder Series AVS carburetor as it will cause corrosion of the fuel system components. It can also cause
rapid failure of seals, gaskets, diaphragms and pump plungers.
Always check to see if you are using a blended fuel. Although the pump may not indicate the fuel is blended, it is always advisable
to verify the type of fuel the station carries.
• Excessive under hood temperature: Ensure fuel line is not located too close to heat sources such as the exhaust or block, causing
expanding fuel to be forced past the needle and seat. Fuel can also boil inside the carburetor due to missing gaskets, spacers, or heat
shields. Also check to see if the exhaust heat riser is stuck, allowing excessive heat under the carburetor. Use Edelbrock Divided Heat
Insulator Gasket #9266 for dual-plane manifolds, Square-Bore Heat Insulator Gasket #9265 for single-plane manifolds, and #9267
Heat Insulator Gaskets for dual-quad manifolds. For additional information on Insulator Spacers, please visit our website at www.
edelbrock.com.
If you have any questions or concerns with the installation or performance, do not return to the carburetor to the
retailer...call the Edelbrock Carb Tech Hotline at 800-416-8628 from 7am - 5pm PST Monday-Friday.
