One problem related to gasoline storage has been reported for the 2000 Mazda B2500. The most recently reported issues are listed below.
I went to a gas station to fuel my truck. Fuel started pouring from the bottom middle of the truck just as the tank reached its fullest capacity. There was no prior incident of fuel leaking before the tank reached its fullest capacity. Nor was there any prior similar experience before this date when filling the tank to its fullest capacity. The fuel was not leaking from any where near the fuel cap area. It may have been coming from the top of the fuel tank (un-confirmed).
