First auxiliary fuel tank ever… First auxiliary fuel tank ever purchased. Self-installed recently, had to make a quick return trip to collect a trailer. 20 hours each way. The fuel tank technology performed flawlessly (Trax 4), and allowed for one fill-up at the turn around point. Amazing. This allows for capitalization of lower fuel prices where possible, and extended range for road trips. Well done TransferFlow!

Heavy duty and perfect fit !! Purchased a 60 gallon fuel tank for my pickup that other suppliers said wasn't available. These tanks are very well constructed, strong, and precise ! Install was super easy, did it myself ! Everything fit exactly like it should !!

Excellent design & fuel capacity Excellent design & fuel capacity. Much nicer looking than my old fuel transfer tank w/hose. Also, Transfer Flow tank is perfect dimension for my 5th wheel RV. In addition, Transfer Flow tank is safer due to the fact that there is no hose/pump assembly that can possibly hit the back window unlike the former unit that I had.
