Product Details

The Advanced Engine Design 5565 is a complete 50cc accelerator pump conversion kit designed for Holley carburetors. This comprehensive kit provides the solution for eliminating lean stumble conditions caused by tight converters, large camshafts, excessive intake plenum volume, or low vacuum situations commonly found in high-performance and drag racing applications.

Complete Kit Includes:

  • 50cc pump housing with mounting screws
  • Pump diaphragm
  • Pump spring
  • Pump cam with screw
  • Complete pump arm assembly
  • All necessary hardware for installation

This kit is engineered to provide increased total squirter volume compared to standard 30cc pumps, making it ideal for big carburetors, heavy vehicles, and performance applications requiring additional pump shot delivery. The 50cc capacity ensures proper fuel delivery during acceleration, eliminating hesitation and optimizing throttle response. Designed to make fine-tuning of the accelerator pump shot quick and easy for racers and performance enthusiasts.

Compatible with Holley 2300, 4150, 4160, and 4500 series carburetors in both 2-barrel and 4-barrel configurations.
