- Umbrella check valves help the accelerator pump circuit seal correctly for crisp off-idle response.
- Replacing tired valves can reduce hesitation and help the pump shot behave consistently.
- Genuine-style parts suit Holley and compatible applications listed in the title.
Accelerator pump check valves are small but important because they control one-way fuel flow during the pump stroke, and when they harden or distort you can lose pump shot and end up with a stumble on tip-in. Swapping them during a service is quick and can make tuning far easier, especially on street engines that spend time in stop-start traffic. Use the correct quantity and orientation for your pump circuit.
