Ford F-350 Fuel Tank by Year

The Ford F-350 gas tank capacity ranges from 29 to 48 gallons across the catalog years 1999–2022. The figures describe the span of capacities listed for this vehicle, not a single capacity that applies to every F-350.

Tank size can change by model year and configuration, so the range alone does not identify the capacity of a specific truck. Compare the entry for your year and trim in the catalog table. If the exact figure for your vehicle is not listed, confirm it on the door jamb or in the owner's manual.

Use the listed capacity as a reference for the tank fitted to the applicable year or configuration. Do not assume that another F-350 has the same tank size; check the vehicle-specific information when choosing a replacement or planning a fill-up.
