How too Narrow a gas tank!

after replacing the spare tire well ( doesn't come with gas tank strap mounts)
we haven't decided yet, to run the stock tank or not

kicking around the idea of dual fuel cells in the trunk
with room to still put a spare tire
they make an adapter to mate to the factory filler tube, (tube will need to be shortened)



also thinking to mount a fuel cell in the middle, under the speaker tray,in front of the spare tire
but would be hard to adapt the filltube
