When we bought Rosey (1970 TR6) we were surprised to find that the gas tank
leaked from the top we were in the midwest and were coming home to
California, we found that if we filled up, got back on the highway the stink
would go away after about 25 miles, one gallon??. I sat there wondering of
the gas leaking on the muffler would explode into a ball of flame, but decided
not to mention it for fear of scaring AnnaBelle. It turned out she was sitting
beside me thinking the same about me.
We managed to get home with no explosion and fixed the leak (from the fuel
sensor plate), I know the muffler is not as hot as a manifold, but it seems to
prove that some ignition is required for flames
BTW Shell V10, was the "stinkest" we found
