How many gallons of gas does a 2500 Chevrolet Express van hold?

The fuel tank capacity of a Chevrolet Express 2500 van varies depending on the year and specific configuration (engine, trim level, etc.). There's no single answer. To find out the exact capacity for a particular van, 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 there.

* The Chevrolet website: You can use their vehicle specifications tool, entering the year and details of your specific van.

Without knowing the year and specifics of your van, I cannot give you a precise answer.
