There will be several here that will preach otherwise, but I say no harm done. My significant other(s) made a habit of pumping the wrong fuel into EVERY Diesel (5.7, 300D, 6.2, 7.3, 6.5, 6.6) I've had since day one. It's gotten much better lately, though.
If you have $20 of #2 in it, that's not much, these days. I say fill'er up, bleed it, and run out the fuel. Fill up again at 1/2 tank, and don't look back. Adding a little extra additive in the meanwhile will help with the missing lubrication. The gas at less than 25% won't hurt anything. At all. If it makes you feel better, drain the tank first, but nothing will be gained.
Anyone that believes otherwise can show up with evidence gas has ever harmed a Diesel engine. If the Diesel concentration is too little, the engine just quits. Only damage that can happen is lack of lubrication if the mix is ran for too long. Add some lube, and don't worry about it. Don't worry about changing the fuel filter, either, unless you think you got some dirty gas. If you think you've never ran gas in your Diesel engine, think again. There will be at least 5% in every tank you pump from your favorite supplier, and most of the time much more. Pull a sample and check it out. You may be surprised.
