You probably won't have any issues with operation, but legally they are against DOT regulationsDoes anyone know if using any transfer flow auxiliary tank on a non diesel truck with have any problems? Most are made for diesel but trying to find one for gas that will fit underneath tonneau cover.. thanks
Well idc that’s y I want it under the hard tonneau cover. Lol just as long as it works I’m goodYou probably won't have any issues with operation, but legally they are against DOT regulations
Going to the 33 is definitely the way to go if you just want a little more range and more importantly need all your bed space. My bed sits empty about 95% of the time and the space the 33 gallon tank takes up vs the 26 (which is what I have) is right where my air compressor system will be going in the future. That plus the massive range bump I was looking for is why I went with an external tank. If you’re going to spend the money you get a lot more range/capacity for the price vs converting your factory tank.Right up front, I have very little knowledge on this subject, so please forgive if this doesn’t make sense. But given the cost associated to having an external tank added, wouldn't it make sense to apply that money toward a 33 gallon tank which meets standards, is safer, and can allow adjustments so the the EVAP system doesn’t throw codes? I know there’s a cost differential but seems to have a safer vehicle, while retaining full use of the bed and not dealing with having to connect pump/hose, etc might be worth the extra $???
anyway we can swap the 33 gal for a bigger tank ? underneath?I made a tank from the Bottom 8" of my toolbox for my '08 RAM Bighorn. There are DOT regs, EPA regs,
and the trucks computer to deal with.
DOT needs OEM or better Parts. I used SS braided line with Aircraft fittings.
EPA needs you to pull from the top of the tank, you can't use a drain system.
It has to be a sealed system for the computer. So along with the Transfer Line, you
need a vent line between tanks. I ran both lines to the filler neck with the vent a little higher.
As long as the Fuel gauge goes up and down there won't be a code thrown for a Sender unit
or gauge malfunction. I can transfer mine on the fly while driving.
I am currently adding a AUX tank to my 2021 Ecodiesel of 72 gallons. with the stock tanks 33 gallons,
and getting the claimed 29 MPG that gives me a range of around 3000 miles.

I don’t think anyone makes a larger tank for the 1500’s, most tank upgrades are for long bed (as in 8 foot) HD trucksanyway we can swap the 33 gal for a bigger tank ? underneath?
With the Diesel you have the DEF tank too. If I could have ordered my truck with the 8' bed and 50 gal tank, I would have done it.anyway we can swap the 33 gal for a bigger tank ? underneath?
I look foward to seeing your complete setup, is the tank going to be custom?I made a tank from the Bottom 8" of my toolbox for my '08 RAM Bighorn. There are DOT regs, EPA regs,

Yes. it will be 20"H x 60"W x 14"D. The Filler neck will be accessed thru the Windoors of my Bed Cap.I look foward to seeing your complete setup, is the tank going to be custom?
