Leaking tee z250

Hey guys.
ive found a slight fuel leak. Apparently its common? 
I changed the o rings then found a micro split at the bottom weeping fuel.

The issue is im having a he'll of a time finding the fuel intake tee for my 1980 z250 b1.
parts catalogue says its part no. 92005-1013. From what i understand kawasaki changed it to 92005-1148. 
however this is now a discontinued item. not sure if theres another replacement i can use.

Any help would be greatly appreciated.
I dont know what to do. I cant find a replacement. Not sure if it can be fixed.

If you are stuck and know somebody with a small lathe this is what I did - I ordered some aftermarket alloy items from Ebay which where the wrong lengths when they arrived but it was relative simple to shorten them on the lathe

Thanks. Thats good advice. 

Its looking like I might have to go down that route. I'm not having much luck.

I guess i need to start looking for a similar fitting and a local metal fabrication shop.

This is what I bought, I would also suggest some quality "O" rings (not the Chinese ones that come with the fittings)

For 1977-83 Kawasaki KZ1000 KZ650 Carburetor Fuel Tee Rail 92005-1010 92005-1009 | eBay UK

That Tee looks similar to the Keihin Tee on my 750.  If you can post up some dimensions, I'll check them against a Tee I have here.

That would be nice if its the same fitting. 

Heres the measurements. I did my best to be as accurate as possible.

I'll find one and measure tomorrow, but pretty sure it's the same...

BTW, when posting photos you need to click "insert all"' before posting.  That way the photos show up properly, not stupid thumbnails

The 750 Tee is extremely similar.  Only difference is an overall width of 32.8mm  O-rings are the same.

Hmmm interesting. I wonder if the 750 fitting would have enough material to machine it down to 31mm.

Does it have around 1.8mm to spare? Maybe shave a bit off both ends?

If so im willing to try it. I've temporarily fixed the leak for now. But I 100% need a more permanent solution. 


Edit:
I just realised ive put down overall length 31mm but when I add the separate sections I measured, they add up to 32mm. So its probably not far off. Will look into it further.

You may not even need to shave it.  Go find an aftermarket Tee similar to that one I posted earlier.  That one could be shaved down a couple of mm if necessary.

I know the z250b isnt that popular, but if this parts fits, its a huge win for us.
