[QUOTE=Mountain Dew;213610 ... Why would an air pocket stop the gas flow? There are no loops or high spots in the fuel line. Why doesn't the air pocket rise to the top of the fuel tank?[/QUOTE]

Bubbles can be sticky. Did you ever have to jiggle the sink stopper to burp the drain and get it to drain? It doesn't help the bubble rise when the liquid it's trying to flow thru is moving in the opposite direction.
