... so I will pull the drain plug from the fuel tank to see what's in there.

A word of caution. You said the car had been sitting 20 years. If the fuel tank was not removed and cleaned at some relatively recent point with the drain plug removed or changed at that time, if the original plug has been untouched for 20 years be very careful when trying to remove it. The original steel plug may well have rusted to the threaded tank portion which is only pressed or crimped into the sheetmetal.

If trying to remove the plug without holding the tank portion with large vise grips or whatever gripping tool you can maintain a good holding bite on the tapered sides then the tank portion will likely break loose and turn with the plug. From that point on you will haves a very very difficult to repair leak.

If you do remove the plug, it would be a good idea to replace the steel plug with a brass plug.
