What is air lock? Thanks, Chris Air lock can be different things, but occurs when air somehow stops a pump or drain. Air lock in a suction line may be simply an air leak in the line, or may be a partial vacuum in a sealed tank of fuel caused by not letting air get into the tank to relieve the vacuum. Air lock in a drain won't let water out of i.e. your toilet, when the drain vent, on the roof of your house, gets plugged with snow, ice, leaves or birds' nests. The overpressure in the drain line can impede the evacuation of the water. Vapour lock is when fuel in the fuel line boils and acts the same as if you had an air leak in the pump suction line, preventing a pump from reducing pressure in the intake line sufficiently for ambient atmospheric pressure to propel liquid to the pump.
