ron.dittmer - I agree with your last sentence. I believe what I would do is take my digital camera with flash underneath and take as many pictures as possible from different directions of the area above the gas tank. Enlarge the pictures to enable pinpointing the location of the fuel line and wiring. Then carefully plan the location from above and carefully cut an access hole. That might solve the problem of the tank being full of gas - wouldn't be a problem. You can always take something like an old license plate and use it to cover the hole you made. Cover with carpet. ;)
