What gallon gas tank in your 06 ford explorer?

The 2006 Ford Explorer came in several different configurations, and the fuel tank size varied depending on the engine and other options. There wasn't a single size. To know for sure what size fuel tank *your* specific 2006 Ford Explorer has, you should:

* Check your owner's manual: This is the most reliable source of information.

* Look inside the fuel filler door: The fuel tank capacity is often printed on a sticker there.

Without knowing your specific trim level and engine size, I cannot provide a definitive answer.
