73' B3 340 Duster pro touring build

every so often i liekt ocheck out your build, some cool stuff going on. i liek the sail panel fuel filler, ive seen some cars with the viper cap in the sail panel. i really like that and did think of doing it to my car. it looks good but ive never seen one with the interior finished around it. the fill tube sticks out so far inside the car so there is room for the pump to go in. what would you do about that?
i have to say im not a fan of the late model door handle thing.
