The Transfer Flow 0800116188 40 Gallon Toolbox & Fuel Tank Combo is an all-in-one auxiliary fuel tank and storage box! Increase your fuel capacity and provide a secure place to hold tools, and other accessories you carry on-board your truck. This toolbox fuel tank is computer controlled, and the fuel transfer process is entirely automatic, by the TRAX 3 operating system! Included is a dash-mounted LCD that shows the percentage of fuel in the main and auxiliary tank. The LCD screen will also show you when the fuel transfer is occurring.

Built from durable aluminized steel, this 40-Gallon Combo Tank features a black powdercoated finish, and internally baffled design to prevent fuel sloshing. Transfer Flow Toolbox and Fuel Tank Combos are fully baffled to prevent fuel slosh and should not interfere with most standard in-bed hitches. The handy locking storage compartment will keep your every day work tools, RV supplies, or hunting equipment safe and secure.

40 Gallon toolbox refuel combo
(Louisiana) | April 22nd, 2013
I am disappointed with the valve this tanks delivers. For the price I expected higher quality. Coating/black paint is not smooth and has bubbles and runs. The tool box lid is bolted on with small bolts. The nuts are exposed and with a little time and a wrench the lid could be easily removed. Even if the lid wasn't bolted on it could be popped open easily with a large screw driver or pry bar. Not much security for you pump or tools that you would carry.The included pump retails for $200. 15 mins on and 30 mins off is the listed duty cycle. Stickers say not to run pump for more than 5 mins with the nozzle closed, however the pump manufacture recommends much shorter times. The hose does not have swivels at either end and twist and kinks are a pain in the tail. No filter is included. While it shows the filter in the pictures and the plate in the tool box even says the filter is behind. There is no filter of any kind present. Not even the cheap inline type.I will never again buy anything from transfer flow. While it might be a DOT legal refueling tank the quality and craftsmanship is not what I expected. Save you money and deal with a company that has real customer service and cares about their customers and products.
