Espada III cooling, gas smells

I got my Espada 15 months ago in semi-restored condition with 45,000km and apparently new radiator hoses.A system flush showed no debris, so I refilled normally (air bleed, etc.) but cooling seemed kind of marginal for a while, with both coolant and oil temps touching the double bar mark above 80 degrees C.Still, even without the secondary fan it never overheated even with AC full on.Since then, it has sort of calmed down and now seldom goes over 80 degrees, even in traffic.Maybe the thermostat wasn"t opening all the way. Anyway, cooling is definitely not a problem with this car. But it does smell of gas inside after it sits overnight. I have inspected every inch of the tanks, fillers, vents, overflow tubes, filter, pump, and output to the engine (totally new armored hose) and found nothing wrong.However, there seems to be a vapor capture device on the right tank, and what looks like a carbon canister which vents to the trunk cavity above the right tank through a plastic diaphram thingy that could be one-way valve to the atmosphere.Could this be the source?Maybe the carbon is saturated?Thanks for any suggestions. George Bullwinkel, Hinsdale IL This will be the first thing I need to do when I pick up the 400GT soon, and I would like to hear some advice about the methods used by other owners. Rule of thumb I have used with success is to work your way from the farthest point away from the Master cyl.I have no experience with this style booster in the rear, so I know you guys can help me.
