    Significantly Increase Pump Shot Volume

    Eliminate flat spots off-idle by supplying continuous fuel flow to your accelerator pump across RPM range. Accelerator Pump Kits include pump housing, pump cam, pump arm, molded diaphragm, special spring, and hold-down screws.

    Note: For most applications, a 1/4" spacer (minimum) must be used under the carburetor in order to clear the pump unit

    20-11 - Holley High-Performance 50cc Accelerator Pump Kits is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from This kit has it all! Everything you need to swap to the larger accelerator pump is included in this kit. I tried over and over to tune my carb throwing everything else at it. With my oversize intake, I needed more fuel from the accelerator pump. The 50cc pump kit cured my carb stumble and now my truck runs great! Couldn't be happier.
