Great tank (50 Gal Aux) Great tank, had it installed by one of the recommended installers. I had been using an older gravity tank, however the new GMC I have did not like the gravity tank (crazy fuel guage). Now everything works excellent. Great quality product and clean in bed look (50 gallon aux tank).

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 !!

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!
