Harman Accentra-2 Pressure Switch Tubing Connections

[kmreggio]

Believe it or not my rabbit got into the back of my pellet stove and ate the tubing connected to the barbed tee leading to the pressure switch. I have replaced the tubing but I am not sure where one of the tubings connect. I have looked everywhere online for an image so I know how to connect these tubings correctly and have not found anything. Can someone show me where these tubings connect? An image of the inside back of the unit would be great, although any help would be appreciated. By the way these plastic tubings looks like tubing used in an aquarium. Thanks in advance, Kim

Here's a pic that might help. I don't know where the tube goes from the vacuum switch. Maybe someone else can help us out with that part of it.
