Last time I was under my nav I noticed a large void of space on the passenger side opposite the fuel tank on the drivers side. I was thinking, would it be possible to mount a standard D22 fuel tank on this side of the vehicle and have two tanks? Obviously the exhaust is in the way, but if this could be modified, it looks as if it would fit. I am assuming the tank is mounted on the passenger side in left hand drive versions of the Navara. What would be the necessary clearance between the exhaust and the fuel tank? If this can be solved, it may be a cheap alternative to the seemingly very expensive replacement main tanks. Any thoughts?
