The Transfer Flow 50- and 80-Gallon Diesel Refueling Tanks fit full-size pickups and come with mounting hardware, fuel cap, and rollover valve. The tanks are ideal for manually fueling diesel trucks or equipment out in the field. The refueling tanks are manufactured from 14-gauge aluminized steel for superior rust resistance and strength. They have internal baffles for extra durability and are powder coated black. They are compatible with GPI and Fill-Rite 12V refueling pumps, which are sold separately.
