The Edelbrock vacuum secondary diaphragm with a 2.054 in rod length is a service replacement part intended for popular high‑performance Quick Fuel, Holley and Demon carburetors. It replaces the rubber diaphragm and rod assembly that controls vacuum secondary opening, restoring proper secondary operation. Confirm rod length compatibility before installation to ensure correct secondary timing and throttle response.
