• How Does DeeZee Aux Tank Fill Main Tank of Vehicle
  Hey Eddy, so the DeeMax aux fuel tank part # DZ91752X is a gravity feed design and does not use any pumps. So what does that mean as far as over filling? If the fill line has a check valve built into it then you are okay to leave it open as that would prevent it from over filling. If there isn't a check valve then you'd have to open it, let the tank fill till it's near full and then close it.

• Transfer Tank /Tool Box Options with Soft Tonneau Cover
  The TruXedo TonneauMate Truck Bed Toolbox Crossover Style # TX1117416 is perfect for any truck owner with a tonneau cover. The toolbox fits under tonneau cover, mounts at the front, back or middle of the bed, and is elevated for full access to the truck bed floor. The dimensions are 55.38" long x 22.25" wide x 14.75" deep. I was unable to find a transfer tank tool box combo under 18 inches tall. All the combos that fit your 2015 Ford F-350 Super Duty are taller than what you want.

• Why Does Valve for the DeeZee Connector Kit 97962 Have to be Closed During Travel on 2016 Ram 2500
  The reason that the valve on the Connector Kit # DZ97962 would need to be closed with the Auxiliary Tank # DZ91752X installed on your 2016 Ram 2500 is because DeeZee didn't design it to work that way and it may cause check engine alarms to go off.

I also asked her if they had heard of any issues with Ram models that don't have the fuel cap filler tube and she said that they haven't heard anything about this. This auxiliary tank is great...

• Can The DeeZee Truck Bed Auxiliary Tank DZ91752X Be Used With Regular Gasoline Instead Of Diesel?
  Hey good question, Roger. The DeeZee Truck Bed Auxiliary Tank # DZ91752X is not intended to be used with regular gasoline.

• Is Condensation Something to Worry About with Aluminum Fuel Tank
  It's like drinking cold water out of a metal cup. The condensation is on the outside of the cup where the temperature change and air are but your drink doesn't get watered down since it doesn't form condensation on the inside of the cup. It's worth noting that condensation on the outside of a tank does not mean there's same condensation on inside of tank. Air is a great insulator and if you consider the fact that the air trapped in the tank is going to stay same temperature as the fuel...
