Larger tank
I'm aware that f150's can come with a 36 gallon tank. Could those be used to swap my paltry 26g tank? Looking for a reasonable way to do this without buying a grand worth of tank and was thinking a wrecked one. Im not a fan of in bed tanks either.
Thanks.
Thanks.

If you're willing to work and fabricate enough, you can make anything fit. The reason the diesel trucks have a small tank is that the 5gal def tank is mounted next to the 26 gal fuel tank.
Try to find a used Titan tank or fabricate your own way to fit the 36gal tank from the other trucks.

I think Ford programmed in a buffer to protect the HPFP and other fuel system components.
I filled up at 26 MTE once (when it was new) and hit 21 gal in but I've never seen 22 on a receipt for example.
The engine derates when fuel is low, probably 0 MTE but there is still fuel left to protect itself from poor operator decisions.
That's my guess on filling a near empty tank.

My MTE showed 24 and it took 22 gallons. I have noticed that the gallons consumed (trip meter) is pretty close to what it will take. I reset the A trip meter every tank. The B trip meter has never been reset. It has 1 mile less than the truck has on it, kind of a overall mileage report.

That's my biggest peeve with the tank too, sure it says 26 gal, but in reality the actual usable capacity is only 20-22 gals, and that's pathetic.

I have on one occasion put 33.1 gal in my tank and the low fuel warning had just activated about a 1/2 mile before I pulled into the station..

Big tank are nice except the shock when you fill it up.
Filled mine up yesterday it was just passed ½ full and it cost me $102.00
Never get use to these fuel costs these days , hell when I was a young fellow that was a weeks pay check.

I pay around $300 for 70 gallons when I fill up!
With the extra tank I can use "gas buddy" and find the cheapest fuel around. A 5¢ savings per gallon really adds up quickly.
By the way, the gas buddy app is very cool.

Back on subject, Ford does make a DEF relocation kit. I was going to order it for my chassis cab, but the DEF tank location was changed on Job2(chassis cabs) to inside the bed rail instead of outside the left bed rail. This probably would be backwards for your situation. However, if you are going to hang big tool boxes under your flatbed you need the DEF tank out of the way.
The point I'm trying to make is you can get the relocation kit and move the DEF tank where it is out of your way. I don't know about anything else that you might need to check before trying to install a bigger tank. I use RDS tanks and have for 9 years.
You can use a small in bed tank and either gravity feed or use a small Airtek pump and RDS install kit and transfer the aux tank fuel to the stock tank. I do this and hook it up to upfitter switch #3. I hope you find a method that will work for you, it sure is great to have more fuel capacity. I only fuel twice between Kansas and Travis AFB California. Those two stops are the lowest price diesel on the 1800 mile trip.
Good luck, let me know if I can help in any way!!
