You need to drain the tank.
1. The rear seat lifts up. You can access the low pressure fuel pump on the top of the gas tank. Remove it and siphon the gas out.
OR
2. Siphon the gas out Via the fuel filler neck old school. There is a trick to the fuel fill flap anti siphon gate but thats the easier route. You just gotta dispose of the contaminated fuel. Have a 5 gallon can of fresh gas to refill.
Dont Drive it imho. You can do more harm than good.
