Default Deciding to build

I recently posted in FAQ regarding selling my 05 STi. I just canít see myself selling the car that gave me the most joy I have ever experienced from a vehicle. Plus, I am in no rush to get rid of it or in dire need of the money from the sale.
I have decided to hold on to it and save up for a DIY rebuild. I am not planning on rebuilding the short block myself, I will get the stage 2 short block from IAG and take the heads to a machine shop that services Subaruís. I have been doing quite a bit of research as I want to educate myself as much as possible before starting this.
The only thing I have not found is information on cars that sit with gas still in the tank. The motor is pulled so there is no way of putting any additives in the lines, I havnít put any additives in the tank to combat condensation and sheís been sitting for a few months now. This build will probably take some time (10mo. - 1yr minimum) to complete.
What is the worse possible outcome of letting gas sit like that and is there anything I can do now to prevent any negative effects from happening?

Thanks for any input on this

Nothing bad is going to happen if it doesn't sit forever. I had gas sit in my WRX for 10 months and nothing bad happened.

I drained the tank pretty easily when I was finished with the build. If you connect the two green test mode connectors (in my WRX they are underneath the dash near the steering column, they might be in a different spot in your car) and turn the key. DON'T TRY AND START THE CAR!!! The fuel pump cycles on and off. Put a hose on the fuel return line near the fuel filter and put the other end of the hose in a gas can. The gas pumps right out.

I dumped the old gas into my 95 wagon, lol.

If you tank is like mine, there are two bolts on the bottom of the tank (one left side, one right side). Take them out and drain the tank. Just make sure to seal things up properly when you are done.

Most likely they are coated with the rubber spray coating, so a little hard to see, but they are there.

My friend's 04 WRX race car has them but my bugeye doesn't. May have been a change with the blobeye. 02 forester doesn't have it either.

^Wagon or sedan? Mine's a wagon. Maybe the bolts are there and I just didn't see them.

I have an 02 sedan and 03 wagon. Both have the bolts. These are "saddle" tanks, so there is a bolt on each side. On mine, they were facing the back of the car, about an inch from the bottom of the tank. Since I originally posted, I have looked around a little and found that some vehicles don't have these drain plugs. Is yours one of those, don't know, but if you run your hand on the lower back side of each side of the tank, you'll know pretty quickly. And as I said, mine were covered by the rubberized sealant. I had to get that off before I had access to the bolt.

Like everybody else is saying, nothing bad will happen. Just drain it. Good luck with the build!
