I happen to agree with- TooFast4SHO and a bit off Topic but find it beneficial to always keep your tank FULL and to Keep the gas tank at least 1/4 full. This much gasoline, a 1/4 tank, keeps the fuel pump surrounded by gasoline, which helps keep the fuel pump cool.
Running the tank less than 1/4 tank depletes this "coolant" and allows the fuel pump to run hotter. It is this heat from the pump, in addition to the ambient heat, that literally distills the gasoline in the tank. This precipitates out the solids and the sludges, which plugs the fuel pump filter. Having at least 1/4 tank of gas in the tank reduces all of these risks,just my 2 cent. Z
