Fig 6-9 Feeder/booster unit, example (DAAE006659)
Fuel feed pump, booster unit (1P04)
The feed pump maintains the pressure in the fuel feed system. It is recommended to use a
screw pump as feed pump. The capacity of the feed pump must be sufficient to prevent
pressure drop during flushing of the automatic filter.
A suction strainer with a fineness of 0.5 mm should be installed before each pump. There
must be a positive static pressure of about 30 kPa on the suction side of the pump.
