Hello, I have a 6n2 with the engine code AHW (1.4l, 16v, 55kW). I was looking for vacuum leaks and I found out a hose that is connected to the fuel pressure regulator but the other end of that same hose isn't connected to anything. I want to find where it goes, help!

First Welcome to the Forum.

 

The hose should connect to a pipe on the end of the inlet manifold near to where the MAP/IAT sensor is fitted 

Somewhere on the inlet manifold or brake servo vacuum hose that the far end will reach to?

#13 is the pipe from the pressure regulator 

Success!
With your responses I was able to find the desired location and connect the hose were it belongs. (I ended up changing the entire hose because it was deteriorated at the other end). Thank you for your help!
