Questions & Answers

What is the difference between a 30cc and a 50cc engine?

The 30cc is approximately 7 mm in diameter. The 50cc has a diameter of more than ten millimeters.

Is it possible to use this 50cc pump diaphram with a Holley 5200?

I believe you should be able to, but you may require the hole kit; the 50cc pump housing kit is required for the 5200 30cc pump. I couldn't get images of both setups to load.

Is it possible to replace the 30cc with a 50cc on a 390cfm?

The Holley 20-inch is required to run a 50cc pump on a 390cfm. Conversion kit for a 1150cc motorcycle.

Will this product work with my 4777 Holley 650 carburetor?

Yes, but you'll have to invest in a 50cc accelerator kit.

Selected User Reviews For Holley Carburetor Diaphragm, 50cc

For California gasoline, this is a good solution

5/5

After two years of California gasoline, the black rubber diaphragm in my Holley failed, so I switched to the green version. Just make sure you order the correct size; there is also a smaller 30cc version. Fix is very easy. Simply detach the carb, turn it over, remove four screws from the cover, remove the old, install the new, replace the cover, and reassemble the carb. It was a perfect match. It will take you less than 30 minutes to complete this task.

Direct replacement that works well

5/5

I couldn't find a suitable replacement in my area. Since 1998, I've been using this for the Holley Carb that came with my boat.
