Just To Be Clear - RDS' Transfer Tanks can be used as auxiliary tanks for diesel powered trucks, however, RDS Diesel Only Auxialiary Tanks are designed for use only as Auxiliary Tanks and will not accept a pump.
Hook Up Easily - These gravity feed kits are a simple and economical way to integrate your auxiliary tank into your diesel pickup truck's fuel system. These kits contain everything you need to make the connection from the auxiliary tank with a 3/8" NPT bottom fitting to the factory fill tube. The auxiliary tank keeps the factory tank full. When the auxiliary tank is empty your factory fuel gauge will move off the full mark. These kits are supplied with detailed instructions and take less than an hour to install. There are no wires or switches to install, engineered for rollover protection and only requires attaching the kit supplied 3/8" npt pipe fitting on the bottom of the tank in place of the drain fitting and splicing the filler neck adapter into your truck's fuel tank filler tube.
You'll Need A Tank - An RDS Auxiliary tank will extend your drive between fuel stops. With choices from 40 to 91 gallon capacities, adding even the smallest RDS auxiliary tank can cut your stops in half. DOT certified, so you know the quality is built-in - By Law. Not to be confused with "Transfer Tanks", these rectangular auxiliary tanks are not designed to be used with external pumps but designed to connect your RDS auxiliary diesel fuel tank to your trucks' OEM tank through the fuel filler tube. Once hooked into your fuel system your truck's fuel gauge will read full until the aux tank is empty. The gravity feed system automatically controls the fuel level going into your OEM tank. As long as the truck's fuel cap is in place the system is sealed and working.
