I accidently poured about 4-6 ounces of simple green into my gas tank thinking it was gas after working on my motor. It's a square 30 gallon tank on a party barge. Any ideas on how to get it out would be appreciated. What would happen if I simply did nothing? All responses welcome. I'm thinking it is water based and might be sitting in a clump on bottom of tank. If so, I might be able to remove the gas line fitting from center top of tank, insert siphon hose, and try to pick it off the bottom. Any thoughts on that approach?
