Diesel Fuel Tanks

OC DIESEL offers a huge selection of diesel fuel tanks for Dodge Cummins, Ford Powerstroke and GM Duramax trucks form two of the finest fuel tank manufactures in the country, Transfer Flow and Titan.

Midship Replacement Fuel Tanks

A midship replacement tank replaces the original factory fuel tank. The benefits of having a larger capacity fuel tank allow you to go further for a longer period of time without stopping and without taking up any additional space in the bed of your truck. Buying a larger fuel tank is one of the best aftermarket purchases our customers say they've ever made.

In-Bed Tanks

For those of you who are not concerned with taking up some of your bed space, having an In-Bed fuel tank may be the best option to gain more onboard fuel. If you are in need a lot of fuel you may choose a midship tank along with an in-bed tank. In-bed tanks come in several different sizes and gallon displacements. Choose for a wide variety of aluminized steel, aluminum diamond plate or plastic in-bed fuel tanks. Transfer Flow offers their TRAX 3 computerized fueling meter to accompany their in-bed fuel tanks. This unit allows you to know when and how much fuel is being transferred from the auxiliary tank to the midship tank.

Toolbox Combos

The toolbox fuel tank combo is a popular item amongst people who want a secured storage container and a fuel tank in the back of their bed. They come in an assortment of sizes and finishes. Some sit below the bed rail and others above. See more by clicking on the image above.

Refueling Tanks

Mostly used on work trucks out in the field, having a refueling tank is a great way to increase convenience and productivity without stopping what you're doing out on the job site. We offer all the optional accessories available for the refueling tanks.

After Axle Tanks

An after axle tank is one that installs after the rear axle of the truck. In many cases, the fuel tank is an added tank to the existing one, however not true in all cases. Some trucks only have an after axle tank that is small or delaminating internally. The aftermarket after axle tanks we offer here are larger and better than the factory tanks originally sold with your vehicle.

Spare Tire Tanks

Spare tire tanks are similar to the after axle tank in where they are located, however your truck was most likely not sold with a fuel tank option in place of a spare tire. Titan Fuel Tanks is the only company to offer the spare tire tank at this time. It has been a hit amongst the guys who have the tire gate installed where they do not use the space under the bed for a spare tire.
