Vapor lock is when the fuel boils on the suction side of the fuel pump and the pump no longer is able to pump liquid. A cure for vapor lock is to mount an electric fuel pump in the tank, submerged in liquid fuel. Since our cars have the fuel pump in the tank, submerged in liquid, it is impossible to have vapor lock. Vapor lock was prevalent on cars with a mechanical fuel pump mounted on the wngine. The long fuel line from the suction of the pump to the tank was subject to road and engine heat (and effects of jigh altitude). The fuel would vaporize in the reduced pressure on this suction line and and the fuel pump could no longer supply fuel to the carburetor. Electronic fuel injected cars NEVER have vapor lock.
She may likely have a clogged strainer on the suction of the pump (in the gas tank) and under long climbs, the pump cannot deliver the pressure and volume needed. Our Contours are known for this problem. I recently cleaned mine for the same type of problem.
