Glad it helped!

thank you

[@kurtpasewaldt]

You're welcome

[@markfeuerherdt2338]

What about the diaphragm on the bottom? Mine is leaking from both. What kind of repair for that one? Thanks.

[@kurtpasewaldt]

You are going to need to take off the carburetor to get to the bottom diaphragm.

[@markfeuerherdt2338]

Also, mine is a 2 barrel MC 2100 carburetor on a 1980 CJ5 jeep with a 258 inline 6 engine. Is diaphragm specific? Thanks.

[@kurtpasewaldt]

I suggestion when looking for parts to look up your specific year of the vehicle to find the correct part.

[@danboy.213]

I have the same carburetor. In a 78 Lincoln mark v. and I thought it was my acceleration pump gasket I replaced it and to come find out my carburetor is leaking from the bottom it’s 4 bolts right underneath the acceleration pump any idea what that is any insight will be helpful the gas in leaking onto my intake manifold.

[@kurtpasewaldt]

If the carb is leaking between the carb and manifold it could be the gasket.

[@danboy.213]

@@kurtpasewaldt ok thank you

[@danboy.213]

What’s the 4 bolts under the acceleration pump. That where the gas coming from soon as I turn on my car I can feel the gas leaking from underneath

[@mickeyantes9607]

Where did you get the replacement diaphragm and what is it's part number? Thanks.

[@kurtpasewaldt]

The diaphragm was part of a carburetor rebuild kit I bought a few years back. You can google Carburetor Accelerator Pump Diaphragm or Walker Products 15369D Carburetor Kit. Just make sure it fits your model carburetor. Hope that helps

[@fredknowles5784]

what problem did this fix? just the leak? or some other indicator?

[@kurtpasewaldt]

Just the leak. Gas would drip onto the manifold.
