 Never clean O-ring with solvent.
 Check that O-ring and its mating part are free of foreign
material.
 When installing O-ring, be careful not to scratch it with
tool or fingernails. Also be careful not to twist or stretch
O-ring. If O-ring was stretched while it was being
attached, never insert it quickly into fuel tube.
 Insert new O-ring straight into fuel tube. Never twist it.
b. Install spacer (3) to fuel damper (4).
c. Insert fuel damper straight into fuel tube.
CAUTION:
 Insert straight, making sure that the axis is lined up.
