I have a 2001 CTD with a 6-speed. The previous owner had a BLUDOT air brake (Vacuum) system installed. I am returning the trucks vacuum system to stock. My question is the line that comes out of the vacuum pump, Where does it go? It currently comes out of the pump and tees off. The one leg has a 3/8 hose and a check valve and continues to the add on air brake controller, the other leg is very small and goes up to the firewall and appears to be stock. If anyone with a stock setup could forward me a photo, that would be great. I have the full set of shop manuals and it doesn't give a good schematic, description of the hoses, or photo.

Pretty simple, they just cut the big line and put in a tee. You can just put in a coupling or new hose and you'll be set. Only thing the vacuum runs is the HVAC and 4wd, small line is all it takes..

 

It may have been T'd for an exhaust brake.

 

Use that tee and put in a JAKE Brake, best thing I ever did, I even use it when I'm not towing
