My first question is why. But I understand answer will prolly be why not. It could be done I'm sure but doing so changes gastank design and will limit trunk space sum as well. It's your car do you and be unique but document it. I love blowing millenials mind pulling up to any pump since my fill is in the back so I don't have to wait for a right or left pump because they both work. I work at a gas station and you wouldn't believe the lines that form because people only wanna fill at the pump on the left but those reaches to other side. But be away having one side or the other could become a pain in more ways than one.
