While changing out the vacuum valve (valve block, vac. distribution block) on my 1994 c280 in the parking lot of the dealer (right after buying the part) I found one of the lines broken. One of the nice techs came to my aid and helped me fix it and change the block. I am concerned he put one of the lines in the wrong location. I can hear vacuum from the block where I could not hear it before. Does anyone have a list of the colored lines (gray, white, black w/ orange stripe, etc) and the corresponding number they plug into on the valve? Specifically looking for the gray line but would appreciate them all!

thanks!
