How do you clear a blocked fuel pipe?

To clear a blocked fuel pipe, first, ensure the engine is off and the vehicle is safe to work on. Disconnect the fuel line from the fuel tank and use compressed air to blow out any obstructions, taking care to wear safety goggles. If the blockage persists, you may need to remove the fuel filter and inspect it for clogs. Finally, reassemble the system and check for leaks before starting the engine.
