Sportster broken carb tube

[karljohn]

The bike I have is a 2001 1200c sportster

I bought the bike used, I am having a bad backfire out of the carb at different times when I ride and lose almost all power then resumes right away.

I was going to check and see if I had a manifold leak on the carb and when I took the gas tank off I noticed this broke piece of tubing. In my manual it looks like it is labeled as the vacuum fitting but I am unsure.


I am fairly sure it is broke and not supposed to be just hanging like it is. Can somebody help me identify what The broke tube is
