Auxiliary Fuel Tanks

Auxiliary fuel tanks are ideal for providing extra fuel storage, keeping it close for when you discover you need it to fuel a vehicle, machine, or piece of equipment. The auxiliary fuel tanks here include a broad spectrum of sizes, purposes, and features. The tank sizes here range from 20 gallons to 63 gallons; dimensions range from 20in.L x 14in.W x 18in.H to 60in.L x 20 1/2in.W x 9in.H; and shapes include rectangular and wedge. Outlet diameters are 3/8in. One of the bestselling auxiliary fuel tanks here is a 32-gallon rectangular aluminum diamond plate unit. The aluminum construction of this tank is rust-resistant, so it won't taint fuel. Seams are fully welded for durability, and this unit is 100% pressure tested and submerged to test for leaks. Designed to transport diesel, water, fertilizer oil, and biofuel, this tank is not for use with gasoline. The lockable automotive-style fill cap adds safety, and a 3/8in. drain with plug can also be used with RDS install kits. The return fitting is a 1/4in. coupling plugged with an aluminum plug. The top-mounted visual gauge allows easy reading of the fuel level. This auxiliary fuel tank also includes a rollover vent valve. One of the largest auxiliary fuel tanks in this mix is a 63-gallon aluminum diamond plate wedge-shaped unit. This tank is DOT-approved and an ideal option for fifth-wheel applications, as its wedge shape at the top works with a fifth-wheel hitch. This auxiliary fuel tank includes a plate for installing a remote gauge (not included); an ROV vent valve; internal baffles to reduce fuel shifting; a lockable fuel cap; and mounting hardware. This tank is designed for diesel fuel only and is not for use with gasoline. Whichever auxiliary fuel tank you select, please be sure to comply with local, state, and federal requirements about the safe transportation, loading, and discharging of fuel. As you browse these auxiliary fuel tanks you'll find products from some of the top brands in the auxiliary fuel tank business.
