You may have luck with penetrating oil but don't hold your breath. Others have tried a hot air gun along with the penetrating oil with hit or miss luck. The plugs are usually rusted pretty solid. I would advise removing the tank, pouring the old gas out and doing a cleaning. If you don't want to do that, then possibly the large capacity filter in the line near the tank as was discussed in another thread would trap the majority of rust thru a few tanks full.

If you do try and remove the plug, make sure to hold the threaded portion on tank with vise grips, a pipe wrench, or something with a good bite when trying to remove the plug. The tank portion is essentially pressed or soldered in and will twist loose without too much effort. Once that happens, there is a leak with no easy repair.
