WARNING:
Be sure to read “General Precautions” when working on fuel system. Refer to FL-16, "
General Precau-
tions" .
1. Perform the procedure from 1 to 7 in “removal” of FL-19, "
FUEL LEVEL SENSOR UNIT" .
2. Drain fuel more from fuel tank if necessary.
CAUTION:
Because fuel tank forwardly inclines and becomes unstable when installing/removing, fuel should
be drained if found the remaining quantity.
3. Remove exhaust center tube and insulator. Refer to EX-2, "
EXHAUST SYSTEM" .
4. Remove propeller shaft, Refer to PR-3, "
REAR PROPELLER SHAFT" .

5. Using a transmission jack, support the bottom of final drive
assembly.
6. Remove the mounting nuts on the rear suspension member, and
lower the transmission jack carefully until just before the rear
suspension member is removed from the stud bolts on the vehi-
cle.
7. Disconnect fuel filler hose, EVAP hose and vent hose at fuel
tank side.
Instruction for quick connector of EVAP hose. Refer to FL-19,
"FUEL LEVEL SENSOR UNIT" .
8. Disconnect connector of fuel transport pump and remove bolts
for bracket.
9. Remove fuel tank protector.
10. Remove fuel tank band mounting bolts while supporting fuel
tank.
CAUTION:
Sustain the bottom of the tank by using plate or anything
same.
11. Remove fuel tank.
CAUTION:
Pay attention not to fall fuel tank because it forwardly
inclines and becomes unstable.
NOTE:
It is desirable that more than two technicians work together.
After lifting down the front portion of fuel tank, remove the fuel tank by pulling it from the upper front of
final drive assembly, so that the fuel tank can move forwardly.
INSTALLATION
Note the following, and install in the reverse order of removal.
Surely clamp fuel hoses and insert hose to the length below.
Be sure hose clamp is not positioned on swelled area of fuel tube.
Tighten fuel hose clamp so that the distance between its lugs becomes to the following.
Fit mounting band pin to the vehicle side securely.
Before fixing the fuel tank, temporarily install the fuel filler tube.
CAUTION:
Use genuine fuel filler tube mounting bolts or equivalent. Make sure to tighten them to the speci-
fied torque.
To connect quick connector. Refer to FL-19, "FUEL LEVEL SENSOR UNIT" .

Checking Exhaust SystemEBS00AZ6
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.
If anything is found, repair or replace damaged parts.
Removal and InstallationEBS003DN
CAUTION:
Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance and shape.
Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.
Be careful not to cut your hand on the insulator edge.

REMOVAL
Separate each connection as necessity.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Always replace exhaust gaskets and seal bearings with new ones when reassembling.
If insulator is badly deformed, repair or replace it. If deposits such as mud pile up on insulator,
remove them.
When installing insulator avoid large gaps or interference between insulator and each exhaust
pipe.
Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gas leakage.
Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.
When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.
Install seal bearings at exhaust front tube and main muffler as follows.
CAUTION:
Do not mix the bolt and spring for seal bearing as the dimension is different for each seal bearing.

4. Gasket 5. Exhaust tube 6. Exhaust front tube
7. Exhaust bracket 8. Mounting rubber bracket 9. Mounting bracket

Exhaust Front Tube Side (QR20DE and QR25DE)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with
exhaust front tube flange.
Main Muffler Side (QR20DE, QR25DE and YD22DDTi)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with main
muffler flange.
INSPECTION AFTER INSTALLATION
With the engine running, check exhaust tube joints for gas leakage and unusual noises.
Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.
