Slide the element base over the center tube (See
Fig.1) and press down.
If it is tight at the bottom, apply one or two drops of
fuel at the point marked in Fig.2
Press down near to the center (not the outside) to
avoid risk of breaking the element base.
The element is already impregnated with a special
filter oil. As this oil is very sticky, take care, when
handling it, to prevent dust or dirt adhering to the
element, especially to its inner surface before
insertion of the center screen.
If your fingers become contaminated, wash them with
soap and water.
NOTE: During storage, the oil may have become
unevenly dispersed through the element. This will
be indicated if the blue color of the element
material appears patchy.
In this case, place the element in a small plastic
bag and gently rub the element between finger
and thumb to redistribute the oil.
Now insert the cylindrical center screen into the
element, followed by the center tube.
Do not, at anytime, omit the screen: it is essential for
releasing air to the engine evenly.
Attach the end plate, washer and retaining screw,
making sure that the element fits correctly between
the end plate and base.
Press at center.
