The labor rate book calls for 2.5 HRS. You can replace them in an hour. Make sure to have all windows down. The car will smell like a gas station for a while otherwise.
I recently replaced both units in my 2013. I've had an issue since I bought it where occasionally, I hit the starter button and it dies a second later. If I cycle through off, accessories and start with my foot off the brake, it will then start just fine. It will sometimes do it when the car is cold, but more often when hot. After replacing both fuel pumps, I'm still having the issue. I bought the car over two years ago and it has done it ever since I first obtained it.
