I haven't actually remove the fuel tank, and doubt that I will, but in studying the iso there appears to be no crossover tube for the two-sides of the fuel tank. Since the tank sits atop the drive shaft (why oh why didn't Nissan make the 370Z FWD
) the tank actually has two sides to it. On other vehicles this has presented a problem with misreading fuel gauges. There are two fuel gauge sensors in the fuel tank.
