    CVP's exclusive Harley Accelerator Pump Diaphragm replaces worn or cracked diaphragms on Harley CV and Harley Keihin butterfly carburetors. Perfect fit, no more stretching or misaligned seals.

    • Greater resistance to mild fuel additive exposure commonly found in pump gas.
    • Will outlast many standard diaphragms when minimal Ethanol* enhanced fuel is occasionally used.

    Sold individually, diaphragm only.

    Replaces Harley p/n 27361-76A found on 1988-2006 CV40, 78-89 Harley Keihin "butterfly" style carburetors, and S&S Super E/G carburetors (p/n 11-2282).

    * Never use fuel that exceeds 5% Ethanol, 10% Methanol, or mixed alcohol additives in a carbureted motorcycle, and do not store vehicle more than 30 days with ANY fuel containing any Ethanol or Methanol. Prolonged use of Ethanol enhanced fuels will greatly shorten the life of any diaphragm, seal or hose. Avoid using fuel system cleaners such as Seafoam or intake cleaners, or replace diaphragms/seals after use. Never use E75, E85, Flex-Fuel, or any fuel that contains greater than 10% Ethanol or other additives.

    Fit perfect and just works great. I replace mine every season because of the harsh fuel additives here in my state. These seem to last longer than the old stock ones I had and fit better than the imports.
