How do you fix ford 6610 air lock?

To fix an air lock in a Ford 6610, start by identifying the source of the air in the fuel system. Begin by checking the fuel lines, filters, and connections for any leaks or blockages. Then, loosen the fuel line fittings at the injectors to allow trapped air to escape while cranking the engine. Once fuel flows steadily without bubbles, retighten the fittings and start the engine; it should run smoothly if the air lock is cleared.
