If you flip the gas cap over, you will see what it looks like in the first picture below. In order to properly drill the cap, I had to cut off the first dimple of the cap, as shown in the second picture below. A cheap and easy way to do this is to shove the cap bottom-first into a bench grinder till it's gone
