As a large language model, I don't have a 1999 Chevy Blazer, or any physical characteristics for that matter. The fuel tank capacity for a 1999 Chevy Blazer varied slightly depending on the specific trim and configuration (2-door vs. 4-door). To find the exact fuel capacity for *your* 1999 Chevy Blazer (or one you're interested in), you should check:
* The owner's manual: This is the most reliable source.
* The fuel filler door: The capacity is often printed on a sticker inside the fuel filler door.
* A reliable online resource: Websites like Edmunds or Kelley Blue Book might have specifications for different 1999 Blazer trims.
Expect the fuel capacity to be somewhere between 17 and 20 gallons.
