Mid 80's 25 xd carburator part

[Jkbutler1]

Hi,
I have a mid 80's 25 xd. There is a small tube that runs vertically and through the center of the Carburator body that appears to connect to the jet and plug at the bottom of the bowl (pn# 6201 and 9171). I have been unable to identify or find the part # for this tube. Do you have any suggestions?

What is the serial number from your motor? This is located on the mounting bracket where it bolts to the transom and is also located on a freeze plug on the motor its self.
