Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hi, my name is ***** ***** certified automotive professional with over 25 years experience. I will be glad to assist you with this.If you need to drain the tank completely and get it clean you will have to remove the tank from the vehicle completely.
If you only need to get most of the gas out you can siphon it out with a siphon pump, you can get the siphon pump at most hardware and auto supply stores.
Let me know if you need the tank removal instructions.
