Chevrolet Silverado 2500 Fuel Tank by Year

The Chevrolet Silverado 2500 gas tank capacity listed here ranges from 26 to 34 gallons across the catalog years. The range reflects variation in the listed specifications, rather than one capacity that applies to every truck.

The catalog covers model years 1999 through 2004. Tank capacity can differ by year or configuration, so use the number associated with your specific truck rather than treating the range as a single rating. The available facts do not identify which capacity belongs to each year or trim.

If you need the exact capacity for your vehicle and it is not shown in the catalog, confirm it on the door jamb or in the owner’s manual.
