Product Details

This throttle bypass has a -8 AN inlet a -6 AN bypass and is easy to install and rebuild. At idle and off-idle the bypass stays open allowing excess fuel to return to the fuel cell to prevent carburetor loading and flooding. As the throttle opens the bypass valve closes to give the carburetor full fuel pressure and volume.
