Vacuum lines at the air filter housing.... 95 Turbo...... 850


Hi all. I'm going through the vacuum lines on my 850 Turbo Wagon and replacing anything that looks suspect (seems like nearly all of the hoses and joints, actually). I was wondering if anyone knew the destinations of the hoses located on the bottom of the air filter housing. There are 3 color coded vacuum outlets, unfortunately I am not sure if mine are located correctly. I was hoping someone would know the actual line-up for the three in regards to the colors on the vacuum distribution device.


Any help is greatly appreciated!

These lines work with Turbo & ECU: Yellow = waste gate Red = Manifold Pressure Blue = bleed line
