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.
