ABSTRACT:
A method for testing vapor recovery units having phase II capabilities for integrity, blockage, or both is disclosed. The vapor recovery unit is modified for vacuum testing. To test the integrity of the unit, a vacuum is drawn in the unit to a predetermined level whereupon it is monitored for decay over a predetermined period of time to ascertain whether the unit is leaking. To test for blockage, a vacuum is continuously drawn in the unit while the lines associated with the phase II capabilities are disconnected from the dispensing station at the point most proximal to the station. Flow of fluid induced by the vacuum is then measured and compared to the desired rate of flow to ascertain the extent of blockage, if any.
