Safety instructions for the fuel supply
• The fuel must not be conveyed by gravity or
overpressure in the fuel tank.
• Withdrawel of the 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. 4.0 bar, use a pressure reducer (order
no. 22 1000 20 08 00) or a separate tank
connection.
• When the pressure in the fuel pipe is more than 4.0
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.
