Water in tank 2004 Pontiac sunfire
If you are talking quarts or gallons, have to drain the gas tank all out and discard the gas, fill with fresh gas. If you think it is just condensation moisture, add an Isopropyl base product, (Heat) NOT a Methanol base. Isopropyl will actually break down the water.
