+1 on the brake reservoir overflow hose, it would be exposed by the washer tank in wheel well. It would be a rubber braided 4mm that connects to the res. and then to a hard solid plastic line along fender in trunk, connects back to the clear section vinyl hose that gets held in place with a folding tab next to washer tank towards the ground. One thing for certain make sure that brake fluid res. hose has a path to the pavement, there could be fluid in that braided section of hose that will spill inside the trunk.
As for where the “vent hose” connection, I don’t recall seeing one when I removed my old yellow hardened and clogged lines.
