Holley 26-41 Umbrella Check Valve for Accelerator Pumps

The Holley 26-41 is a replacement umbrella check valve designed specifically for carburetor accelerator pump circuits. This small but critical component ensures proper fuel flow direction during acceleration, preventing fuel from flowing backward into the fuel bowl when the accelerator pump is activated.

Key Features:

• Umbrella-style one-way check valve design
• Prevents reverse fuel flow in accelerator pump circuits
• Direct replacement for worn or damaged original valves
• Compatible with Holley carburetors using umbrella-style check valves
• Ensures crisp throttle response and proper acceleration

When accelerator pump check valves wear out or become damaged, symptoms can include hesitation during acceleration, poor throttle response, or fuel leaking from the pump discharge nozzle. Replacing this inexpensive component can restore proper carburetor performance and eliminate these issues.
