I've had this warning for a while. The brakes work fine so the booster itself is not actually faulty. Research online tells me that the most likely cause is a leak in the vacuum lines from the brake booster vacuum pump to the brake booster. I took the time to trace these lines last night, the best I could in a fly-infested garage, and found one cracked plastic pipe. I sealed it up with electrical tape and zip-ties but the warning came back on this morning after about 1 mile of driving. I don't know if it's the same spot or not.

What I want to do is replace the entire set of vacuum lines relating to the brake booster. But there are two problems with this plan:

1. I do not know quite what is required. The PET is not clear and does not seem to quite exactly match my car. Illustration 604-00 is the only one that seems to relate to the brake booster system and it includes the pump, the booster, and two vacuum lines. But when I inspected mine there was first a vacuum line from the pump toward the front of the car, down to the floor, then out toward the quarter panel, then back around toward the engine, then back up toward the hood, then back toward the firewall where it connected to another line. This appears to be #14 in the illustration (part 955.355.579.01 or its ilk). But mine has some kind of a T fitting with another line attached to it underneath where it loops around for no apparent reason. Does anyone know what I'm missing here?

2. I have no idea how to replace item #13 from the illustration (part 955.355.577.01 or its ilk). This appears to go back into the bowels of the car where everything is impossible to reach. It appears that you need to remove at least one of the windshield wiper assemblies to remove the lid to this compartment and even then I have no idea how much of a rat's nest I would be looking at. This is the part that included the crack that I found so it definitely needs replacement. Has anyone dealt with this area or maybe even this specific part before? I don't want to dive in unless I know where I'm going.

The alternative is to have a dealership do this for me, but the nearest one is 400 miles away so that is not ideal. Thanks in advance.
