Datsun-240z Vs Fairlady-z432

[kats]

Hi Captain! I was thinking about you!
If I were you, I was able to take it off easily and put a perfect piece for the vacuum. 
You have skills and professional tools! 

Do you mean the remaining piece can be pulled out by using some tools like an ultra micro sliding hammer (I don’t even know such a tool exists)? or drilled (scraped) out by a drill bit?

About the cylinder, yes my current cylinder is made by NABCO but I want TOKIKO lock type cap which looks period correct for my June 1972 car.

Hi Kats, I know you look at eBay in the US.  Are these too expensive?

Hi Kats, If I were trying to get that piece out, I think would use a small tap to thread the inside of the brass piece. Then once there were threads inside, I would use a screw as a handle and try to pull it out. I would also make a small arbor that I would put between the screw and the carb body. I have made similar adapter arbors in the past and I will take a picture tomorrow of something similar.

Also, I've messed with other similar fittings on the carbs and they are usually very tight, I would use heat before I tried to pull it. Small butane torch.

And if all that fails, I would use progressively larger drill bits and drill out the brass until I could pick out the small pieces.

Thanks inline6, eBay selling the cap! But it is expensive for me. Japanese currency is now way low compared dollars, I can’t enjoy shopping from USA anymore. 
 

So I have got a set of the cap at a local car workshop. They were a half of money which I would pay for the one on eBay.

Great!! Using a tap and a screw, and apply some heat. Those methods would never come up in my mind. 
 

Thank you Captain! I have learned new things today, it will be helpful for my future restoration work.

Kats, Here's some pics showing what I would try:

You're starting with something like this. This is a different carb, but the situation is the same:

Tap some threads inside the hole. You may have to drill it a little first to the appropriate pilot hole for the tap. This is an English 4-40 tap, which is close in size to M3 x 0.6:

Then I made a little puller adapter to concentrate the force in the perpendicular direction to pull the brass slug out of the carb body:

Put it over the brass slug and carefully run the screw in:

If everything goes according to plan, it should jack the brass remnant out like this:

If it doesn't come out easily, maybe try a little heat from a small torch:

And if that doesn't work, you might be able to get the piece out with a drill like this:

Thank you Captain!! You show how we can go through the challenges. I remember you did some amazing work 

when I was wondering about the Works wheel nuts.
