There is a page on snopes about this exact email.

In summary,
Item 1. may save you $31 a year
Item 2. Is considered to be negligible
Item 3. May save $62 if you could completely eliminate evaporation.  And 
  this doesn't take into account the MPG loss due to carrying more 
weight in your car.
Item 4. Gas stations are required to have filters, so you make make your 
car's filter work a little harder, but you're changing that regularly 
anyway right?
