Frequently Asked Questions:

1. How do I know if I need a 30cc diaphragm? The required accelerator pump diaphragm size (e.g., 30cc, 50cc) depends on your specific Holley carburetor model. Always refer to your carburetor’s specifications or identify the part number of your existing diaphragm.
2. What are the signs of a failing accelerator pump diaphragm? Common signs include hesitation, a flat spot, or a bog when you rapidly open the throttle, especially from an idle. You might also notice fuel leaks around the accelerator pump housing.
3. Is installation difficult? Replacing the diaphragm is generally straightforward. It typically involves removing the accelerator pump housing cover, swapping out the old diaphragm, and reassembling. Ensure careful handling and proper torque on fasteners.
4. What is the difference between a brown and a black diaphragm? Historically, brown diaphragms were often rubber, and black were often specialized elastomers. However, both colors are now commonly available in various materials. The key is to match the correct pump volume (e.g., 30cc) and ensure it’s fuel-resistant. This product specifies “black rubber.”
5. Do you ship Holley parts throughout South Africa? Yes, we offer reliable nationwide delivery of performance carburetor components across South Africa from our location in Alberton, Gauteng.
6. Do I need to adjust anything after replacing the diaphragm? After replacing the diaphragm, it’s often a good idea to check and potentially re-adjust your accelerator pump arm screw (often called “pump cam screw”) to ensure the correct fuel shot duration and linkage movement.
