When I have a break from delivering packages, I open the hood and look around. This has paid off recently as I have noticed not only a disconnected vacuum line, but also a split Y-hose which had been hopelessly taped together. As you can see from the picture, there was no possible way of fixing what was probably the original hose. Jaguar and Saab must have designed this one together: the hose has three different sized endings! As you can imagine, there was no hope of getting a replacement from NAPA. So, Jaguar charged me $36 and I installed it today.
