How big is the gas tank on a RAM 1500 v8?
The RAM 1500 with a V8 engine typically uses a 26-gallon fuel tank (about 98 liters). This is the standard size you’ll encounter on most V8 configurations, though exact capacity can vary by model year, cab/bed setup, and optional equipment. This article walks through the baseline, potential variations, and how to confirm your specific build’s tank size.
Baseline fuel tank size for most RAM 1500 V8 models
The majority of RAM 1500 pickups equipped with a V8 engine use a 26-gallon tank. This figure appears in official specifications and owner manuals across a wide range of trims and years, making it the standard reference for most drivers.
- 26 gallons (approximately 98 liters) is the standard fuel-tank capacity for most RAM 1500 V8 configurations.
In practice, the 26-gallon figure covers the baseline for many builds, but there can be exceptions based on year, cab and bed dimensions, and optional equipment. Always verify the exact figure for your specific vehicle in the window sticker or owner's manual.
Variations by year, cab and bed configuration
While 26 gallons is the baseline, some configurations or model years may differ. The RAM 1500’s cab size (crew cab, quad cab) and bed length can influence available tank options, though the 26-gallon figure remains the common reference for most V8 models.
What typically drives variations
Variations in fuel-tank capacity are usually tied to the vehicle’s configuration and market-specific options. Rarely will a RAM 1500 V8 shipping configuration deviate significantly from the 26-gallon baseline, but certain packages or regional editions can alter the exact capacity. Always check the exact spec for your build.
- Cab-and-bed combinations and optional equipment may affect the tank size in some cases.
- Special editions or region-specific variants might use a different capacity, though this is uncommon for North American RAM 1500 V8 models.
To avoid any guesswork, consult the vehicle’s window sticker or the owner's manual for the precise capacity of your specific RAM 1500 V8.
How to confirm your RAM 1500's exact tank size
