    There is an in tank pump that primes and feeds the main pump. The main pump is known as the High Pressure Fuel Pump HPFP or Cam Driven Fuel Pump CDFP. There are threads here and on the MazdaSpeed Forum with all the definitions and abbreviations. The HPFP provides fuel to the direct injection injectors at around 1800psi straight into the combustion chamber.
