3.5.1 Fuel suction using a fuel suction hose.
Fuel is taken directly from the fuel tank of the vessel or an
additional tank. Drill a hole Ø16mm in the fuel tank to install a
fuel suction hose. When drilling the hole in the fuel tank, follow
safety precautions that should be observed when working with a
vessel, which is filled with fuel or explosive substance.
Cut the immersible tube of the fuel suction hose shorter
before installation (if needed). Its bottom end must be located
about 10-15 mm above the bottom of the tank, or at the height
to provide fuel for engine in the fuel tank at any time. The cut at
the end of the fuel suction hose must be made at a 45° angle to
the axis of the tube. Remove all burrs from the cut after the work
is done.
Install the fuel suction hose in the fuel tank as per Fig.13a.
Install the special washer of the fuel suction hose in the tank hole
as per Fig.13b. Apply a petrol-proof sealant on the threaded
surface of the fuel suction tank to properly seal the connection
between the fuel suction hose and the fuel tank.
