Symptom/Condition, Diagnosis & Parts Information
SYMPTOM/CONDITIONEngine performance is gradually reduced in high ambient temperature or high altitude driving due to a drop in fuel pressure, which starves engine for fuel (goes lean). Engine may not start until fuel system components cool off.
DIAGNOSIS
The following ore characteristics of vapor lock and should be observed on a fully wormed up engine. (Vapor lock does not affect cold engine driveability.)
^ Occurs after hot soak, prolonged idle, or highway speeds at any throttle opening.
^ Sag due to lean mixture.
^ No black smoke at tailpipe.
^ Fuel pressure drops to 0.
^ Carburetor air horn dry.
^ No accelerator pump discharge.
^ May not start until engine cools.
^ Engine may not sustain heavy loads.
