If the inside of the fuel tank is to be cleaned, use any one
of the following:
(1) Kerosene
(2) Trichloroethylene
(3) A neutral emulsion type detergent
FUEL TANK PRESSURE CONTROL VALVE
(1) Remove the fuel tank pressure control valve.
(2) Check the valve function after a clean rubber hose is in-
stalled on it.

15. INSTALLATION OF FUEL TANK PRESSURE CONTROL VALVE
Install so that the fuel tank pressure control valve is facing
in the direction shown in the figure.
14./4. CONNECTION OF VAPOR HOSE/3. RETURN HOSE
When attaching the fuel hose to the pipe, be sure that the
hose is attached as shown in the illustration.
Standard value : 25-30 mm (1.0-1.2 in.)
10. INSTALLATION OF SELF-LOCKING NUT
Tighten the self-locking nuts until the rear end of the tankband
contacts the body.

9. CONNECTION OF VAPOR HOSE/8. FILLER HOSE
(1) The vapor hose should be connected all the way at the
tank, and approximately 40 mm (1.6 in.) at the fuel tank
filler tube.
(2) The end of the filler hose with the shorter straight pipe part should be connected at the tank side.
7. CONNECTION OF HIGH PRESSURE HOSE TO FUEL
PUMP
Temporarily tighten the flare nut by hand, and then tighten
it to the specified torque,
bein,g careful that the fuel hose
does not become twisted.
Caution
When tightening flare nut, be careful not to bend or
twist line to prevent damage to fuel pump low connec-
tion.
FUEL PUMP REPLACEMENT
(1) Disconnect the fuel pump connector.
(2) Remove the fuel tank filler tube cap.
(3) Drain the fuel.
Ml3GFAt.X
(4) Disconnect the fuel high pressure hose and main pipe.
Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
(5) Loosen the self-locking nuts to the end of the stud bolt.
(6) Disconnect the lateral rod right side body coupling; then
lower the lateral rod and use wire or similar material to
suspend from the axle beam.
(7) For models equipped with the ACTIVE-Electronic Control Suspension
(E.C.S.) disconnect the rear height sensor and
the lateral rod. (Refer to GROUP
33B-Service Adjustment
Procedures.)

(8) Remove the fuel pump installation screws and the bolt for
holding the fuel pump (at the lower side of the fuel tank),
and then remove the fuel pump from the fuel tank.
(9) Align the three positioning projections of the packing with the holes in the fuel pump.
(lO)When the fuel pump is installed, the holding bolt at the
lower side of the fuel tank should be installed first. Care should be taken at this time that the O-ring is not
pinched.
(1 l)For models equipped with the ACTIVE-E.C.S., check the operation of the ACTIVE-E.C.S. after installation of the rear
height sensor. (Refer to GROUP

SERVICE POINTS OF REMOVALMlSKBAMl
1. 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 caused by some residual pressure
in the fuel pipe line.
3. REMOVAL OF FUEL FILTER (1) Loosen the main pipe flare nut while holding the fuelfilter nut securely.
(2) Remove the fuel filter mounting bolts, and then remove the fuel filter from the bracket.
INSPECTIONMlOKCABl
l Check the hose and pipes for cracks, bend, deformationand clogging.
lCheck the evaporative emission canister for clogging.
l Check the fuel filter for clogging and damage.
SERVICE POINTS OF INSTALLATIONMlJKDAPl
6. INSTALLATION OF FUEL VAPOR HOSE/4. FUEL RE-
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 fuel hose to the pipe securely, so that it is the
standard value.
3. INSTALLATION OF FUEL FILTER (1) When installing the fuel filter, first temporarily install thefilter 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.
TSB Revision 2. INSTALLATION OF HIGH PRESSURE FUEL HOSE
Apply engine oil to the hose union.
Insert the hose, being careful not to damage the O-ring, and
tighten securely.
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.
