Has anyone installed an auxiliary fuel tank in the bed of their truck?
I have a 2019 F250 diesel crew cab with the short bed.
Just wondering if you had problems and solutions.
Thanks.

You'll also need to install an electric pump if the auxiliary is connected to your factory tank.

I had a 100-gallon Transfer-Flow tank in a long-bed 2008 Ford F350 diesel. One small problem (if you even call it that) was that the amount of fuel on the display was always less than what was in the tank -- I would have about 20 gallons left when it displayed 0 gallons.

Another slight problem was that leaves and debris that collected in the one-inch space behind the tank were difficult to remove.

I recently traded for a 2021 long-bed diesel, and want to get another Transfer-Flow when one becomes available for the 2021 Fords. I do it for peace-of-mind; so that I can tow for three for four days without constantly having to worry about fuel; so that I can reach Yellowstone (for example) at the end of a driving day and still enjoy driving around for the next couple of days without having to think about visiting a station. To me, that's worth 50 cents a day spread out over ten years.

You do NOT get a transfer tank to for the purpose of finding cheaper fuel (you never save enough to get your money back), but a side benefit is that you have the option of topping-up whenever you happen to see a good price, or you can keep on trucking though a state where fuel is more expensive. But, as I said, that is secondary to peace-of-mind.

Metal transfer tanks will have a good deal of water condensation. I put a water-separation filter in the line coming out of the transfer tank. That helped to keep water of out the main tank and not overtax the truck's own water-separation filter.

Go to Transfer Flow dot com and run your truck through the options. You might be able to get a larger tank to replace the one you have now, or one to sit under the truck bed somewhere.

They also have a lot options for an in-bed tank, anything from a fuel only tank to one that shares space with a toolbox.

I very much agree with Roy's comments, save for the leaves part; my tank is fully under my tonneau cover. I too have a steel tank but don't have an additional water filter and haven't had any water in fuel issues, even after leaving it empty all winter. I put an inline electric fuel shutoff with a dash switch for easier control of when the auxiliary flows into the main.

Give Transfer a call and they will recalibrate your tank gauge.

My wife bought me an auxiliary fuel tank for Christmas quite a few years ago. A 36 gallon tank with a separate filler pump nozzle. Cost was around $500 total. One of my best Christmas presents ever. I love stopping when I want to, and not when the truck says I have to. Take our breaks at rest areas, and city parks instead of gas stations and truck stops.

I have used a 95 gal RDS gravity flow tank in both Chevy and Ram trucks, no issues what so ever. They just connect to the filler pipe about 12 inches down and have a check valve to prevent overfilling. I always just put fuel in the large tank and go, over the years I have saved many a dollar in fuel costs, sometimes up to a dollar a gal by bypassing a state where fuel is extremely high and not having to refuel until you want to is a big plus. Wouldn't tow without one.
