Gas Tank Overflow

[ramiro@ctt.bellcore.com]

Hi Erich,

I had the gas tank of my replaced at 32,000 miles because it had a
leak.  The only way to figure it out was to get under the car and look
for the leak because it wasn't big enough as to leave a trace on the
parking lot.  The reason for the leak was a faulty pressure valve.
The pressure built up in the gas tank until the gas tank gave up.

Occasionally I smell gas in my car.  However, it goes away with no
problems so I don't pay attention to it.

   Howdy, I've got an 85 4000 Quattro CS with 85K on it.  Last night
   I noticed the smell of gasoline from the rear right quarter of car,
   naturally around the gas cap.  I parked the car overnight on dry
   pavement, and the next morning there were no leaks on the ground.
   The tank is pretty much full (20 miles on that tank), and we've had
   some funky weather around here lately (40 degrees to 70 in 12 hours).
   I called a garage and they seemed to think that the temperature
   may have caused the gas to expand and flow out of the cap through
   some leakage valve.  Has anyone had this happen to them before?
   Does this sound reasonable to people?

   Thanks,

   -Erich
