When connecting the fuel-pressure regulator to the deliv-
ery pipe, apply light oil or petrol to the O-ring, and then
insert, being careful not to damage the O-ring.
3. CONNECTION OF THE HIGH PRESSURE FUEL HOSE
When connecting the high pressure fuel hose to the
delivery pipe, apply petrol to the hose union, and then
insert, being careful not to damage the O-ring.

FUEL FILTERREMOVAL AND INSTALLATION3.2.INSTALLATION OF FUEL FILTER
(1) When installing the fuel filter, first temporarily install the
filter to the filter bracket; then insert the main pipe at
‘*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.

Caution
Because there is high pressure applied between the
fuel pump and the injection mixer, be especially sure
that there is no fuel leakage in this area.

SERVICE ADJUSTMENT PROCEDURES
REAR WHEEL ALIGNMENT INSPECTIONN17FAAC
The rear suspension assembly must be free of worn, loosen or
damaged parts prior to measurement of rear wheel alignment.
Standard value:
Toe-in (Left-right difference)
Of3 mm (Of.118 in.)
Camber-45’ + 30’
NOTEThe rear wheel alignment is set at the factory and cannot be
adjusted.If toe-in or camber is not within the standard value, replace
bent or damaged parts.
WHEEL BEARING END PLAY ADJUSTMENT,7FBA0
1.Inspect the play of the bearings while the vehicle is jacked
up and resting on floor jack.
2.Remove the hub cap and then release the parking brake.
3. Remove the caliper assembly and the brake disc.
4. Check the bearing’s end play.
Place a dial gauge against the hub surface; then move the
hub in the axial direction and check whether or not there isend play.
Limit: 0.01 mm
(.004 in.) or less
NOTE12AO531If the limit value is exceeded, the lock nut should be
tightened to the specified torque and check the end play
again.
5.Replace the rear hub bearing unit if an adjustment cannot
be made to within the limit.
