Vacuum line size Help - Page 2

Unfortunately I don't have my GZ anymore so I can't trace it. Maybe someone else will jump in. It would seem to me if the line were off of the carb you would hear a hissing sound from the carb and the engine would run rough. Look for a capped off niple on the carb. Ride safe.

Doing some more research I found a picture of the carb and put a circle around the nipple.

Yes, to discuss the picture above, the nipple is on top of the carburator tube to the cylinder, right at the rubber hose to the cylinder. So you should push the hose down onto the nipple.

And at the fuel valve, it connects at the carburator side, but you already knew that.

Thanks Mole 2, and thanks 5th_bike. I did find it and tried the 7/32'' ( 5.5mm) hose. That one fits perfect the nipple by the petcock, but it does not fit the nipple on top of the carburetor as that nipple is very small. So my question is what is next: Do I have to buy a vacuum connector right? or is there an specific type of hose? a smaller size did not fit the nipple by the petcock. thanks for all the help...

Go to Autozone and get one of these: AutoGrade Vacuum Connector and use two pieces of tubing of two different sizes.

You could also order the hose, it's Suzuki part number 13686-13F10

And the clip (for tightening it at the little nipple; there is no clip at the petcock) is part number 13671-13F00

I feel like 4mm would be a proper hose size.
