On some cars there is a hump on the top of the tank for a vent, with a similar hump in the trunk floor for it to fit into. On my original tank, this area was flat but because of rust I had to replace it. I was planning on moving the tank over as well, trouble was, I could only get a new tank that had the hump in it so I couldn't move it over unless I modified the tank and/or trunk floor.

For now, the exhaust just dumps as the axle but I want it to go to the bumper.
