Caution!
Safety instructions for the fuel supply!
• The fuel must not be conveyed by gravity or
overpressure in the fuel tank.
• Withdrawal of fuel after the vehicle’s fuel pump is
not allowed.
• When the pressure in the fuel pipe is more than
0.2 bar to max. 2 bar, use a pressure reducer
(order no. 22 1000 20 09 00) or separate tank
connection.
• When the pressure in the fuel pipe is more than
2 bar or there is a non-return valve in the return pipe
(in the tank), a separate tank connection must be
used.
• When using a T-piece in a plastic pipe, always use
support sleeves in the plastic. Connect the T-piece
and the plastic pipe with corresponding fuel hoses
and secure with hose clips.
