Holley 50CC Accelerator Pump Cover Housing & Screws - HO26-140

• Accelerator pump cover restores a proper seal and lever action on 50cc pump assemblies.
• Includes the lever and screws listed so you can replace worn components in one hit.
• A fresh cover helps keep the pump shot consistent and reduces the chance of leaks around the housing.

On Holley-style carburettors, the accelerator pump is critical for clean tip-in and it also sees regular servicing as cams and diaphragms are tuned. A damaged or warped pump cover can cause seepage and inconsistent pump action, so replacing it is a smart move during a rebuild. Fit it carefully, ensure the diaphragm is seated correctly, and set the pump arm clearance to suit your setup.
