Fit the tube into which the cable is to be installed into the air box and tube
clamp.
It is recommended that a length of tube similar in size to the tube into which the cable is to be installed be fitted
in the tube clamp. This length of tube may then be connected to the installed tube (the length of tube
underground into which the cable is to be installed) using a suitable connector.
Slide a suitable size O ring over the end of the tube.
Fit the tube into the end of the air box housing so that it protrudes approx. half way into the housing, position
the O ring so that it sits against the seal face, as shown in the illustration below.
Once the tube has been positioned, the
tube clamp may be closed, the swing
bolt swung down and the thumb nut
tightened, the tube is now secure.
