Vacuum Line pipe part number
 

After being "sold" the wrong part at the dealership, I thought I'd post the CORRECT part numbers for inquiring minds. This way you can avoid making a second trip or argue with a "vintage challenged" parts counterman.

Vacuum line pipe (clear, underhood engine compartment):
000-158-14-35 0001581435

Vacuum line pipe (clear, door locks, etc.):
001-997-39-52 0019973952

I may have unknowingly bought the wrong part from a guy with 1 year of experience 10 times, rather than the guy with 10 years of experience.:D
