I looked online for other images of gas pumps in PR and the other photos did not include a green section on the pump. Perhaps my best bet is to somehow get an actual photo of a Puma gas pump on Highway 66 in PR between Farjado and San Juan. Of course, I'll have to figure out how to get something like that, but I'm hoping that the photo UnderEst provided is not what those gas pumps look like along Highway 66.
