Harley Accelerator Pump Diaphragm

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, CV44, and S&S Super E/G carburetors (p/n 11-2282). Will also fit CVK40 carburetors equipped with a bottom-mount accelerator pump. 

Not guaranteed to fit on non-Harley model carburetors. Not for use on smaller Keihin CVK, S&S A or B, or other non-Harley model carburetors. S&S Super E and G are registered trademark(s) of S&S Cycle and CV Performance is not affiliated with S&S Cycle©

* Never use fuel that exceeds 5% Ethanol, 10% Methanol, or mixed alcohol additives in a carbureted motorcycle. 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, gasket or hose. Avoid using fuel system cleaners such as Seafoam or intake cleaners, or otherwise replace diaphragms/seals after use of cleaners. Never use E75, E85, Flex-Fuel, or any fuel that contains greater than 10% Ethanol or other additives.
