Increase your driving range with the RDS Auxiliary Diesel Fuel Tank and Toolbox Combo! Auxiliary tanks can be used as an additional capacity for a factory tank with the use of an RDS Diesel Install Kit (sold separately). Connect the Diesel Install Kit to the bottom of the Auxiliary Tank to gravity feed diesel fuel to your OEM fuel tank. You can shop for better fuel prices with this increased range. It is made from no-rust 0.125” heavy-duty aluminum with fully welded steams. Built-in baffles reduce sloshing. The lid covers the toolbox as well as the fuel fill to prevent tampering. The toolbox section is reinforced with welded lid braces. Two gas filled lift cylinders assist in opening and holding open the toolbox lid. Two stainless steel paddle handles (1 locking) are linked together so you can open the lid from either side. The tank meets DOT standards and comes with a gas cap, withdrawal coupling, drain fittings, manual sight fuel gauge, and a fuel filler shroud.
