system in the following manner:
1) Loosen the fuel filter connection pipe (eye joint) tightening bolt
of the fuel pump.
2) Turn the feed pump handle top to the left, and the handle will
be lifted by the internal spring.

through the eye joint.
4) Repeat the feed pump operation until fuel coming out of the
eye joint does not contain air bubbles. Tighten the eye joint
tightening bolt, push down the feed pump handle and screw it
in.
