What is an accelerator pump diaphragm and why is it important?

The accelerator pump diaphragm is a critical part of your carburetor. When you press the gas pedal, it squirts a small amount of extra fuel into the intake manifold, preventing hesitation or bogging as the engine's demand for fuel increases.

What carburetors does this Edelbrock diaphragm fit?

This diaphragm is specifically designed for 4150-style carburetors, which are common in many performance and classic applications. It's also compatible with Holley, Demon, and Quick Fuel carburetors that use this style of pump.

What does '50cc' refer to on this diaphragm?

The '50cc' refers to the volume of fuel the accelerator pump is designed to deliver with each squirt. This is a standard size for many 4150-style carburetors, ensuring the correct amount of fuel is injected for optimal performance.
