I am using Fuel CMS 1.3.1. When I create a new page using the interfacca is possible to insert a block. As you can select the block created in the appropriate menu Thank you
You can use the {fuel_block('my_block')} in a text area field to insert a block, or you can create a block layout and use the block field type as a field type for your page layout:
