When the fuel is being sucked from the vehicle tank, or an independent tank,
a suction pipe is required. Make sure all the openings are appropriate for the

The bottom of the suction pipe should be about 30-40mm from the bottom of
the fuel tank so as to avoid sucking impurities or sediment from the bottom
of the fuel tank.
