ABSTRACT:
This invention tests the mechanical integrity of an evaporative purge system and fuel system by applying a vacuum to a fuel tank and measuring the extent to which this vacuum bleeds down over a time period. Included in the test method are the steps of closing the vapor management valve positioned between the engine manifold and the evaporative purge flow path of the fuel tank; waiting a predetermined period of time; and obtaining an indication of the extent to which pressure is increasing in the fuel tank due to vapor generation.
