What is the gas tank size 1992 Chevrolet G20 Van?

I do not have access to real-time information, including vehicle specifications. Therefore, I cannot provide the gas tank size for a 1992 Chevrolet G20 Van.

To find this information, I recommend checking the following sources:

* Your Vehicle's Owner's Manual: This should have the gas tank capacity listed.

* The VIN (Vehicle Identification Number): You can use your VIN to find detailed specifications on websites like Carfax or AutoCheck.

* Online Resources: Websites like Edmunds, Kelley Blue Book, and Autotrader often have detailed specifications for vehicles.

* A Local Mechanic or Dealership: They will have access to databases with this information.

Please remember that gas tank size can vary depending on the specific trim level, engine size, and other options.
