Nozzle

In a rocket engine, fuel and a source of oxygen, called an oxidizer, are mixed and exploded in a combustion chamber. The combustion produces hot exhaust which is passed through a nozzle to accelerate the flow and produce thrust.

In a liquid rocket, the propellants, the fuel and the oxidizer, are stored separately as liquids and are pumped into the combustion chamber of the nozzle where burning occurs.

No spray is coming out because the nozzle is clogged.

The app will take care of the payment, but somebody — in most states, the driver — still has to get out and manually insert the fuel pump nozzle into the car's gas tank.
