To find the exact fuel capacity for *your* 2000 Ford F-250, you should:
* Check your owner's manual: This is the most reliable source. The fuel capacity will be clearly stated.
* Look inside the fuel filler door: The fuel tank capacity is sometimes printed on a sticker inside the fuel filler door.
* Check the sticker on the driver's side doorjamb: This sticker often contains information about the vehicle's specifications, including the fuel tank capacity.
Without knowing your specific truck's configuration, I cannot provide a definitive answer.
