Fuel System

I guess this kind of falls under two categories, Carburetors and engine, I have a 1982 KZ 750 4 cylinder that I bought not too long ago, basically in pieces, the carbs are on the bike, but I honestly haven't the first clue as to how the fuel system is setup, if anyone could send me pictures of their bikes or direct me to any sort of guide as to how to do this, I'd really appreciate it. I do have the service manual for the bike, but it doesn't really tell me all that much...

Your book should show you a exploded view of the carb rack including vent lines and fuel line.
The bike is a simple gravity feed fuel system, very similar to the riding lawnmower in your photo. You need a vacuum line to the petcock probably from carb #3 with the out board carbs tied to the EGR and then two vent lines that will run typically down like the overflow tubes or up towards the air box.

Any unused vacuum nipple should be capped. Such as where the exhaust air system has been removed and the nipples are no longer needed.

Good Fortune!
