2003 Acura TL Strange Noise!

Hey guys. This may be a tricky one so I don't know I fyou can help me. I am looking to buy an Acura TL 2003 Type S. Now, the entire car is mint. All Acura serviced and in really good shape. There are just 3 issues with the car. My main issue is that there is this strange ticking sound that is being made near the master cylinder under the hood. It is also making the same noise near a module that is under the car just before the fuel tank. This module has quite a few lines going into it. They seem to be brake lines, but at the same time, seems to be fuel lines that also junction into it. Anyways, I dont really know what the module is, but what puzzles me more is the noise. The seller tells me at the dealer, they said that it is normal for the car to make this noise. But other TL's I have looked at did not have anyhing like this. Any help please?
