Unless a gasoline fuel system fitting is defective, no sealer is necessary or recommended. IF a joint or fitting leaks, the recommended "fix" is to REPLACE the leaking fitting. IN an emergency [only temporarily], and only until the vehicle can be moved to a repair station, one "might" get away with using silicone plumber's tape, or Permatex [brand name] #2 paste sealer. Although I cannot recall competitor's names, there are products equivalent to Permatex. I recall, back in the 1950s, the "olden" days, that we could use well chewed bubble gum for fuel system leaks, BUT in the 60s, the natural gum base in chewing gums and bubble gums was replaced with artificial, man-made gum which no longer worked because they are dissolved by gasoline.
U NEED TO REMOVE THE GAS TANK. CLEAN OUT THE RUST. PUT IN A GAS TANK SEALER. REINSTAL TANK ON CAR.
Teflon is inert to gasoline and all petroleum products. The problem with Teflon is it cold flows under pressure so that when tightened (when wrapped around your fitting) it will relax eventually and probably not seal properly. This is not something you want where gasoline can leak.
Gasoline being poured into a tank is not a chemical change.

This is called siphoning. The gasoline-filled tube, when the end that is not in the gas tank is lowered to a point below the tank, it creates a pressure differential inside the tube. Just as liquid pours from a glass when it is tilted, so does the gasoline flow through the tube. As long as the tube in the tank is below the level of gasoline in the tank, the gasoline will continue to flow until the flow is interrupted (or until the tank is empty).

There is no reason for gasoline to explode in a tank. There is no heat or spark source in there. But the basic answer might be that there is little to no air (specifically oxygen) in the tank.
Yes, because water is heavier then gasoline
It is a tank that holds gasoline.
