I was interested in purchasing an extra fuel tank for my truck. I had a lot of questions. Tim took my phone call and was extremely helpful. He was very knowledgeable, professional and answered all my questions. I have an appointment to have the tank installed.

Fabulous customer service! Tim Wells went out of his way to accommodate my schedule since I was coming from Michigan. (2400 miles away) I have other Transfer Flow products on my older trucks and Tim always help to get me the right parts and advice to service my equipment .

Thank you for your feedback, Jason! We’re glad to hear you had a good experience with our customer service. We appreciate your support and look forward to helping you again!
I had a local company install this tank for me. I heard no complaints from them regarding ease of install. It was nice to be able to point them to the video and on-line instructions so they knew what they were getting into. The tank has been functioning flawlessly in my 2025 F350 7.3L gas pickup. The gas gauge still works. The distance to empty calculation is off. Hopefully someone comes up with a software fix for the late model trucks. Overall, I'm happy with the tank and it does what I paid for - extended my range.
Aaron, thank you for the review! We appreciate you sharing your experience and are glad to hear the install went smoothly and that the tank is performing flawlessly on your 2025 F350. It’s great to know the resources and instructions were helpful for your installer, and we’re especially happy the tank is delivering the added range you were looking for. Thanks again for choosing us, and we’re here anytime you need support!
Candace, thank you for your 5-star review! It's very much appreciated!
Great product and great customer service
We’re glad to hear you’re happy with both our product and our customer service. We truly appreciate your support and look forward to helping you again in the future!
Ordering was straight forward and quick. Customer was friendly, patient and worked with me. Shop that installed the tank was impressed with the build quality and was able to get the install fairly quickly. The profile under the truck is about the same as the skid plate that was removed. The tank metal is heavy enough that there is not need for the skid. Operation we will see. Still need to get the gauge calibrated but that may be more of a Ford issue than Transfer Flow.
Johnny, Thank you for the thoughtful feedback! We’re glad to hear your ordering experience was smooth and that our team was friendly and helpful throughout the process. It’s great to know your installer was impressed with the tank’s build quality and that the installation went quickly. We design our tanks to fit as cleanly as possible, so it’s good to hear the low profile met your expectations as well. We also appreciate your note about the gauge calibration on the newer Ford trucks. Feedback like this is very helpful as we continue to support evolving vehicle systems. Thanks again for choosing us, and we’re here if you need anything as you continue using the tank!

The $2,000 tank is damaged upon receipt!!! 1 massive dent in the back, 1 small dent in the back and the delivery driver threw it off his truck onto the fill cap!!!
Thank you for bringing this to our attention. We’re very sorry to hear about the condition your tank arrived in. That’s certainly not the experience we want for our customers. For freight shipments like this, we do recommend carefully inspecting the packaging and item at the time of delivery and refusing the shipment if there are visible signs of damage. This helps ensure a smoother and faster resolution with the carrier. A Transfer Flow representative will be contacting you regarding your order.

Exactly what I was looking for. American made quality, and the order process was easy. Order arrived in a timely manner.
The Tool Tank box was packed good and came all together. The customer Service team was out of this world. Would buy again.
Jesse, we’re glad to hear your Tool Tank arrived well-packaged and complete. It’s also wonderful to hear our customer service team made such a positive impression. We truly appreciate your support and look forward to serving you again in the future!
I bought a used truck that had a Transfer Flow system in it. I knew nothing about the system so I called up and got to speak to Tim Wells. He explained the system to me and everything I needed to know about it. The truck also didn’t come with the key to lock the box. Tim helped me track down a replacement key for the box. Certainly would recommend this company just based off of service. However, I love the system also and it tremendously increases my fuel range from stock.
Thank you for sharing your experience, Austin! We’re so glad you reached out and that Tim was able to walk you through your Transfer Flow system and get you up to speed. He takes great pride in helping customers, and it’s great to hear he was able to track down a replacement key for you as well. It’s also awesome to hear you’re enjoying the system and the extended fuel range it provides. We truly appreciate your recommendation and are always here if you have any questions down the road!
Ease of installation. Works great, no leaks and a super clean look! Great product! Would be nice to have a vehicle specific template for drilling the 1.25” holes for the hoses. Once I drilled them I struggled getting my hand high enough on a 2026 GMC 2500. Could just be my big hands, but if I drilled slightly lower, it would have been much easier. Can’t complain, it works great and looks factory underneath.
Thank you for the great feedback! We’re glad to hear the installation went smoothly and that you’re happy with the clean, factory-like look and performance. We also appreciate your suggestion regarding a vehicle-specific drilling template. Thanks again for choosing Transfer Flow!
