ATTA AT38RBR-PB Under Bedcover Auxiliary and Transfer Tank

The AT38RBR-PB from ATTA is a 38-gallon rectangular diesel tank designed to stay out of sight—sitting below the bed rails so you can use a hard or soft tonneau cover without any trouble.

 It’s only 12 inches wide, so it barely takes up bed space while still giving you the fuel range you need. Whether you drive a short or long bed truck, this tank fits and works with a transfer pump system of your choice.

The rear driver’s side fill neck is easy to access when the bed cover is open, keeping refueling simple and quick.
