in the pic where the arror i need to know where the vacume lines go, theres like a T split and ive looked at diagrams that i could find and either it doesnt show where they go or im to stupid to fiigure the diagram out.....

 

On my 98 blazer that tube is pointing the other way toward the drivers side and the vacuum hose that I took off goes to the drivers side over the brake booster to a t-fitting where it connects to other vac hoses.

 

Take a look at the front axle clicking tech article for vacuum diagrams.

The fitting on the intake pictured is installed 180 degrees off.

 

I know its not in the right postion i just googled a pic of it since it was to dark to go outside and take one thats on my blazer
