GENERAL INFORMATION
Determine the leak size from the time it took to
reopen the switch. Note: Fuel level is an impor-
tant determining factor.
•
If the switch does not close, a more aggressive
purge flow will be applied to determine if it is a
very large leak, missing fuel cap, problem with
the NVLD device, purge flow problem, etc...
