Re: spider gas vapors

Greg,

Thank you for your response.  Since reading your email, I did some further 
investigation and I want to share to all what I found.  Your explanation of 
the vapor recovery was great and it helped me to solve the problem.

1. I verified that the small diameter hose with a check valve connected 
terminated to the engine crankcase ventilation hose.  It is full of liquid 
gas.  I purged the line by removing both ends from the check valve and from 
the ventilation hose.  I used a blow gun.  Gasoline spurted out of the 
ventilation hose end.
2. I removed both hoses that connected to the side of the plastic vapor 
recovery tank in the trunk.  After removing the lowest hose, gasoline leaked 
all over.  There must have been about half a cup of gas.  The upper hose 
connected to the gas tank.  The lower hose connected to the crankcase 
ventilation hose.  This DID NOT make sense.   Someone mistakenly swapped the 
hoses. (This car was previously painted.)  In theory, the lower hose should 
connect to the gas tank and any liquid should go back down to the tank.  The 
upper hose should be connected to the crankcase ventilation hose.  Vapors 
that come up from the tank will then be sucked from the upper hose and travel 
to the crankcase ventilation hose.  The vapor can then be sucked into the 
intake manifold to get burned.  I verified while the engine is running that a 
vacuum was present in the crankcase ventilation hose that is attached to the 
upper side of the plastic recovery tank.
3. I believe the odor in the trunk was coming from the 1/2 cup of gasoline 
swishing inside the plastic tank.
4. To be safe I will change the oil immediately just in case gasoline got in 
the mix of the crankcase.

Thanks for your help.
