• Items (2), (7) and (11) are included in the “tank

connection“ kit.

• When installing tank connection maintain a

minimum distance of 50 ± 2 mm from the end of the

riser pipe and the bottom of the tank.

Caution!

Safety instructions for the fuel supply!

• The fuel must not be discharged by means of gravity

or overpressure in the fuel container.

• It is not permitted to extract fuel downstream of the

vehicle’s own fuel pump.

• If the pressure in the fuel pipe is more than 0.2 bar up

to max. 4.0 bar, use a pressure reducer (order no.

22 1000 20 08 00) or a separate tank connection.

Installation3

• If the pressure in the fuel pipe is over 4.0 bar or if

there is a non-return valve in the return pipe (in the

tank), a separate tank connection must be used.

• If using a T-piece in a plastic pipe, always insert

support sleeves in the plastic pipe.

Connect the T-piece and the plastic pipe with the

relevant fuel hoses and secure with hose clips.
