Where are the vacuum lines located on a 1999 Dodge Grand Caravan?
Under the hood, they are plugged into the Intake plenum by the MAF.
The only difference between the Dodge Grand Caravan and the Dodge Grand Caravan Sport is mostly aesthetic. The side cladding on the Sport model is the same color as the body of the vehicle, the spoiler is visible, and there are other convenience items. It also has a firmer suspension than the Grand Caravan.
