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).

Everyone at Transfer Flow knows their…Job! Everyone at Transfer Flow knows their job, but more importantly, everyone from the time you open the door until you leave the parking lot is on the same page. Once the first person knows why you called or dropped in, you are taken care of promptly without you having to explain over and over to each person why you are there.

Outstanding Customer Experience I am amazed on how solid this company is. I had an issue with my fuel pump on myTrax4 in-bed tank on Tuesday . I called and spoke with Marti on the tech line and explained what the problem was. I also told Marti that I was leaving on Thursday for a 10 day trip. Marti identified the problem and immediately send out a replacement pump the same day. I received the pump on Wednesday and the install was simple. Marti and the Transferflow team saved the day and now I don’t have to worry about filling my stock 32 gal tank every two hours pull my 5er. I was further impressed with the fact that Marti called me on Thursday inquiring how everything went. Transferflow, you have a customer for life and I will be your biggest supporter! Thank you Robert

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!

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.
