2022 RAM 1500 Lonestar 23 gallon to 33 gallon fuel tank upgrade

[PurpleRT]

I am also looking into replacing 23 gallon tank with 33 on 21 ram 1500 longhorn crewcab, 5' 7" box, looking in owners manual it looks like 33 gallon tank was only available in longbox? Is this incorrect information, also would fuel pump have to be replaced? I love my truck except for the always watching the fuel gauge when towing!

Anyone know how feasible swapping gas tanks would be? My mileage thus far has been pretty terrible and I’m kinda regretting not getting the larger gas tank.

I would think it could dropped in and replace/recalibrate the fuel level sensor.

^ start there has all the information you need.

Yea you would need a new fuel pump for a 26/33 tank

33g was available with both the 5”7 bed and 6”4

Where could find the right fitment for my truck? I have 23 1500 big horn 3.6 v6 with the 26 gallon tank. Im looking to upgrade to the 33. I want to make sure I get the right one before I spend money

I am Welding two 3/8-NPT Bungs (Fuel & Vent) between the tank and the
filler neck. Drilling a hole on the inside bed wall for a grommet big enough
to led the two lines pass. I have a Transfer pump with wires going into the cab
and up to the Overhead console where I installed 6 switches for various things.
The LED Numbers are for a PSI Gauge for the On-Board air.

I did this on my '08 Bighorn with the bottom of the Tool box being the 36
Gallon AUX Tank. I was getting around 950 miles range with the Hemi.

There are DOT, EPA,and the Trucks Computer to take into consideration.
You need to use OEM or Better parts. I used Aircraft fittings and SS Braided lines.
You have to pull from the top of the tank, never from the bottom. If the Fuel
Gauge doesn't go up or down then a code fault will be set in the computer.
I can transfer on the fly as the Gauge works and no codes are set.

Did you make that overhead switch panel yourself? I'd be interested.
