Screw the two M6 x 25 screws to the holder.
Route the 4 x 1.25 mm Ø fuel pipe from the heater together
with the metering pump cable along the fuel lines on the left

Cut the 4 x 1.25 mm Ø fuel pipe to the required length and
fasten with cable ties or clip into the holders.
Connect the 4 x 1.25 mm Ø fuel pipe with 3.5 x 3 mm Ø fuel
hose, length 50 mm, to the discharge end of the metering
pump using two 9 mm Ø hose clips.

tion at the metering pump cable.
Remove the dummy plugs from the mating connector.
Slot the plug-in contacts of the metering pump cable into the
mating connector regardless of polarity.
