For the past few days, there has been a clear fluid leaking from the rear of my car (1997 Honda Accord). It is coming from what appears to be some sort of bleeder hole near the fuel tank. Anyway, I have no idea what the liquid is! It is oily, but clear. Literally no color to it. It has not evaporated after 2 days, so I know it's not water, windshield washer fluid, or gasoline. It is not motor oil, transmission fluid, power steering fluid, coolant, or brake fluid (due to the lack of any sort of color). Any thoughts? Thanks!
