Being that I'm 99.9% sure that my problem is water in the tank, I went to drain the tank tonight with a siphon pump. Never having siphoned fuel, I was unaware that newer cars have siphon blocks or filters that keep a hose from going down into the tank. So, how can I drain the tank? I know some cars have drain plugs, but I didn't see one under mine. Could I possibly unhook the fuel filter, plug a 12V battery up to the fuel pump, and drain it that way? And if the fuel pump is going out, how will I be able to tell?

Add a can of fuel dryer if you think its water. Its a hell of a lot easier than trying to dispose of 15 gallons of petrol. If you have to though you can siphon a 1997 no sweat.

Already used two bottles of fuel dryer at different times in the past week. Didn't help a bit, nor did changing the fuel filter. Plus, I only have about 4-5 gallons in the tank.

Then fill it up with 10 gallons of fresh fuel.
