Major Gas Leak

[JohnD]

So I had the valve cover gaskets replaced a few weeks ago. I have only driven the car about 4 times, in total 450 miles. I had meetings in town today so I took the wifes car and she took my x5 to work. I received a call saying that when she got home the truck started pouring gas all over the garage floor from the front of the vehicle. I rushed home to find the main gas line that goes to the engine wasn't seated correctly and gas was just pouring out. I clipped the line on ad everything appears to be fine, but the house stinks of gas and I had to cleanup about a gallon from what use to be my painted floor. Also while I was in there I removed faring and found that they had epoxied a vacuum canister they broke while they were working on it.. Attached is a pic - does anyone know what it is called. I have already left a nasty message for the service manager, but wonder what follow-up actions I should take. Had this happened while she was on the highway, I am sure the engine would have caught fire... I am so pissed right now
