Great experience... I truly enjoyed my experience with Transfer Flow. I chose to purchase an extended range gas tank from them and have them install it at their facility. From my first phone call to the actual in person appointment. Very friendly office staff. Knowledgeable installers and an overall good atmosphere. Job was done quickly, correctly and everything works as it should. Very happy!

Customer service is horrible Customer service is horrible. I’ve been trying to get ahold of this company for 6 months left voicemails called time and time again never to get a response…

We've had our 50 gal auxiliary tank for… We've had our 50 gal auxiliary tank for a couple years now, it has worked Flawlgadget! Simple Fuel Filter replacement keeps us rolling. We love it, thank you for engineering the best auto-tranfer auxiliary tank and dash gauge! Dave Hayden

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!

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).
