Help with identifying a petcock

I pulled this off of my 1980 KZ1000E2 shaft. I ordered a new fuel tap gasket but what I received does not match up as it has the openings along the circumference of the tap with no middle opening. This would not be the first part on this bike that came off of something else. Anyone out there have any insight as to what this one originally started out on so I can order the correct part? Thanks folks!

Looks like an 80's vacuum petcock to me. I think you need this rebuild kit:

I'm not 100% but that kit covers a lot of models, and they all have petcocks that look like that one.

It is the vacuum petcock. I was hoping to figure out which model so I can buy just the one gasket since I have all the other pieces. I'm working on a pretty tight budget so I'm hoping to avoid a 25 dollar kit just to get a 8 dollar gasket

Its from any of the models listed in that link...

My petcock was fried too. Gaskets were gone, so I got a standard petcock and will get an adapter plate to make it work... when I get money that is. :lol: I didn't like the idea of having a petcock that I couldn't turn off.

Oh, and this is the kit for our bike: www.z1enterprises.com/Petcock-Repair-Kit...100-KZ1000-1670.aspx
It's $55.50
