6. Remove the fuel injector and fuel tube assembly.
 Loosen bolts in the reverse of the order shown.
CAUTION:
 When removing, be careful to avoid any interference with
fuel injector.
 Use a shop cloth to absorb any fuel leaks from fuel tube.
7. Remove the fuel injector (3) from the fuel tube (1) with the fol-
lowing procedure.
a. Open and remove the clip (2).
b. Remove fuel injector from the fuel tube by pulling straight.
CAUTION:
 Be careful about fuel leakage remaining in fuel tube.
 Be careful not to damage the nozzle of fuel injector.
 Never subject fuel injector to impact by dropping or hit-
ting.
 Never disassemble.
INSTALLATION
1. Install new the O-ring to the fuel injector, paying attention to the following.
CAUTION:
 The upper and lower O-rings are different. Be careful not to confuse them.
 Handle O-ring with bare hands. (Never wear gloves.)
 Lubricate O-ring with engine oil.
 Never clean O-ring with solvent.
 Make sure that the O-ring and its mating part are free of foreign material.
 Be careful not to scratch O-ring with tool or fingernails when installing it. Also be careful not to
twist or stretch O-ring. If O-ring is stretched while installing, never insert it into fuel tube immedi-
