Diesel Auxiliary Tanks

Extra diesel for your truck, in ATI tanks from 30 to 80 gallons

A diesel auxiliary tank carries extra fuel for a diesel truck, so it can run longer between fill-ups. Every tank here is an ATI diesel model. Rectangle tanks run from 30 to 66 gallons, the wedge holds 60 gallons and the L-shape holds 80.

Choose by how much extra fuel you want on board and which shape fits the space on your truck. Each diesel size except the 80 gallon L-shape also has a gasoline twin, with a part number ending in G, so check the model before you order. Gas engines need gasoline auxiliary tanks.
