I think it's fairly rare for the CSV to actually leak. In my 
experience, there's almost always something else wrong with the FI 
wiring that actually turns the CSV ON. So gas getting thru the CSV is 
just a symptom of a problem elsewhere. 

It's usually important to find and fix that underlying problem, 
because the open CSV isn't the only thing that's going wrong because 
of it.
