Much of the Inbox functionality is right there in regular gmail. Inbox was too slow for me although I loved using it for quite a while. I use the snooze function a lot in regular gmail and have completely forgotten about Inbox.

If I remember right, there may also be a fuel transfer pump in addition to the fuel pump. This was a similar issue on a Jetta I had. The fuel pump sitting in the tank was fine, the humming and overheating of the transfer pump was the culprit.

Most Volvos have this on the headrest in a similar position to the airline seat.

Note: CMU a small school? Both schools are practically the same size!
