Auxiliary fuel tank in bed of 2016 F350 SWB

[Jim Sweeney]

I want to put an auxiliary tank in the bed so I can pull farther without the need to refill the 26 gallon tank. I have been told that the 2016 F350 has a sealed fuel system, so that I can't use a tank that empties directly into the OEM fuel tank.

I haven't been able to verify this.

Thanks in advance,
Dave
