OF REMOVALN14KSAl.a1. REMOVAL OF EYE BOLT
Remove the eye bolt while holding the’ fuel filter nut
securely.
Caution.Cover the hose connection with
ragS: to prevent splash
of fuel that could be
caked by some residual pressure
in the fuel pipe line.
3. REMOVAL OF FUEL FILTER
(1) Loosen the main pipe blare nut-while holding the fuel
filter nut securely.
(2) Remove the fuel filter mounting bolts, and then remove
the fuel filter from the bracket.
11. REMOVAL OF CLAMP
!After removing the crossmember, remove the clamp.
(Refer to GROUP
2-Centermember and CrossmeTber.),.

TURN HOSE
(1) If the fuel pipe has a stepped part, connect the fuel
hose to the pipe securely, up to the stepped part, as
shown in the figure.
(2) If the fuel pipe does not have a stepped part, connect

‘*the connector part of the filter, and manually screw in
..the main pipe’s flare nut.
(2) Holding the fuel filter nut, tighten the fuel main pipe’s
flare nut and eye bolt at the specified torque. Then
tighten the filter to the bracket.
