Pretty sure he means the whole system. I dunno about 15 minutes, but it's not that big of a job compared to, say, a timing belt. I didn't take the dash apart either. Just some quality time in the Lotus Position (upside down under the dash.) Biggest time sink is bleeding the brakes, although getting the 3 line couplings off was a PITA. A bit rusty on mine. I just unplugged the charcoal canister electrical connections, undid THE ONE BOLT holding it on, pulled up and moved it aside. The bottom hose came off, so pay attention to that.
