Thanks for the reply. Actually, the majority of the fumes, at least the ones the first night that actually got into the house, were from the gas leaking out the filler neck. I plugged that up (again) and the smell wasn't as bad and is at least contained to the garage. The last time this happened I dropped the tank and re-sealed the sender. And the first time I filled up the new tank the sender popped out the top and leaked gas all over the ground.
As I said, there have been many woes. But, that's just with the gas tank. Don't get me started on the rest of the car after 28 years of devotion. Sajeev has actually helped me out with a few of the others over the years.
