RAM 2500 Fuel Tank by Year

The Ram 2500 gas tank capacity ranges from 31 to 35 gallons across the catalog years. The listed figures are a range for the vehicle, not a single capacity that applies to every model year or configuration. Use the catalog entry for the specific year and trim when available, since the capacity can vary within the range.

The catalog covers model years 2012 through 2022. The facts do not identify which capacity applies to each year, engine, or trim, so do not assume the lower or higher figure based only on those details. If you need the exact tank capacity for a particular truck, confirm it on the door jamb or in the owner's manual.
