Thanks for the replies.

The reason I asked is I poured about 1/2 gallon of mineral spirits into the empty tank that has been sitting for 7 years. When I noticed and removed the filter I got about 1 cup of fluid out(right down my arm and into my arm pit causing me to jump into the pool because it burned like a...)

I used mineral spirits because it seemed to attack the glop of sludge I fished out of the carb better than anything I tested on it, including carb cleaner.

So I guess the tank doesn't drain completely through the filter? I was planning on pulling it anyways.
