BTW.... when temps fluctuate a fair bit between night and day, as they do in colder climes in the late fall, early winter, late winter, and early spring (and, here, for the past 6 weeks, the temps have been from minus freezing to what a friggin mess!), water condensation occurs vehicle in gas tanks. If your tank is less than about 3/4 full during these times, you may have a water problem.

Since most companies started placing the fuel pumps in the tanks, most problems with ice in gas lines and carbs have been eliminated. However, this practice does have a downside. Over time, enough water may accumulate to the point where a major problem may occur. That is YOUR downside. But, a great upside for the vehicle manufacturers.
