Clearing a Fuel Tank Obstruction with an Air Compressor

What happens here

Realizing there's an obstruction preventing fuel flow, the presenter fetches a portable DeWalt pancake air compressor and an air blower nozzle. He connects the air blower to the disconnected fuel line and blows compressed air back towards the fuel tank. He confirms hearing bubbling in the tank, indicating that the obstruction has been cleared. After this, he reconnects the external electric fuel pump and successfully observes fuel flowing through the inline filter, confirming the success of clearing the blockage.

Goal: Restore unobstructed fuel flow from the tank.
