Removal likely entails loosening two inside carbs from backing plate.
Some models (such as carbs on Z1 and KZ900) have built-in raised rubber areas which fit snugly into each carb. The raised areas get worn and leak. replacements are available from Z1 Enterprizes. With this style, best repair imo is a new fuel pipe.
An optional repair method is wrapping with teflon tape to tighten the fit. Standard white teflon tape will work pretty good, but yellow teflon tape is also readily available and touted as more fuel resistant that the white version.
Other models use o-rings instead of the built-in raised rubber area.
Good Luck!

Tee fitting is called a "fuel pipe joint."

Am thinking the KZ650 fuel pipe joint is a smaller size and might be more difficult to find.
Good Luck!

According to the schematic on bikebandit.com it is the carb connection shaft, replacement is 65 bucks. But that is for a kz1000, cant find anything for a 650. I'll have to take a closer look but it doesnt look to be threaded so I'm not sure the teflon tape would work. Looks like either way I need to take the entire assembly back off the bike. Oh well, at least I'll get better at putting it all back together. I'm guessing O-rings are the culprit. Thanks for the info.
Would forget any concern with threads. Neither the tee fuel pipe between carbs #2/3 nor the straight fuel pipes between carbs #1/2 and #3/4 have any threads. Don't see any o-rings either.
The teflon tape should work just fine. Wrapped around the raised areas, the tape snugs up the press-in fit on the ends of the fuel pipes where they simply press into the carbs on either side.
Might take a look at the 1977 KZ650-C1 carb assembly on kawasaki.com OR the 1978 KZ650-C2 carb assembly on BikeBandit, and note part #34 (tee joint) and the two parts #36 (straight joint). No o-rings shown.
Here's the image from kawasaki.com.
Good Luck!

The parts description section on BikeBandit's diagram for 1978 KZ650-C2 carb assembly says one tee and two straights are required.
Here's another pic for teflon tape wrapping location.
Good Luck!
