Could be one of the fuel lines is rusted, cracked, or a connection has come loose.
Especially with possible rusting, the outside of the line could just be saturated with gas and not nessesarily dripping.
I know 'cause it's happened to me. Stong smell of gas but nothing on the ground.
Not sure about the backfire.
