WARNING:
When replacing fuel line parts, be sure to observe the following:
lDisplay a ªCAUTION: INFLAMMABLEº sign in workshop.
lDo not smoke while servicing fuel system. Keep open flames and sparks away from work area.
lBe sure to disconnect battery ground cable before conducting service operations.
lBe sure to furnish workshop with a CO2fire extinguisher.
lPour drained fuel into an explosion-proof container then ensure container lid is installed securely.
CAUTION:
lFor ECCS engine models, release fuel pressure from fuel line. Refer to EC section (ªFuel Pres-
sure Releaseº, ªBASIC SERVICE PROCEDUREº).
lDo not disconnect any fuel line unless absolutely necessary.
lPlug hose and pipe openings to prevent entry of dust or dirt.
lAlways replace top lid seal and hose clamps with new ones.
lDo not kink or twist hoses and tubes during installation.
lDo not tighten hose clamps excessively because this could cause damage to the hose.
lEnsure fuel check valve is installed in the correct orientation. Refer to EC section (ªFUEL CHECK
VALVEº, ªEVAPORATIVE EMISSION SYSTEMº).
lAfter installation, run engine and check for fuel leaks at connections.

REMOVAL
1. Release fuel pressure from fuel line.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC SER-
VICE PROCEDUREº).
2. Remove inspection hole cover located under the rear seat.
3. Remove fuel filler lid.
4. Disconnect fuel outlet, return tube and connectors.
CAUTION:
Mark the fuel tubes to ensure correct position during instal-
lation.
5. Using SST KV999G0010, remove fuel gauge locking ring.
6. Lift the top plate from the fuel tank.
CAUTION:
lDo not disconnect fuel hoses from top plate. Top plate
has to be removed together with fuel chamber assy.
lFor CD20T models the fuel gauge sender unit is attached
to the top plate.
QG16DE, QG18DE & SR20DE models only:
7. Remove fuel pump with fuel tank chamber assy as follows:
a. Push the locking clip upwards and slide the pump chamber
assy towards the rear of the vehicle.
b. Lift the pump chamber assy from the bracket.
c. Carefully remove the pump chamber assy and top plate from
the tank.
CAUTION:
While removing the pump chamber assy lift the fuel gauge
sender float, to prevent it from bending.
8. Take off the fuel pump chamber lid by opening out the 4 clips.
Remove the fuel pump from the fuel pump chamber.
9. Remove the fuel gauge sender unit from the chamber by lift-
ing the clip and sliding the sender unit upwards.

CAUTION:
lAlways replace exhaust gaskets with new ones when
reassembling.
Scrape off all residue of old gasket from flange surface.
lWith engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.
lAfter installation, check to ensure that mounting brack-
ets and mounting insulators are free from undue stress.
If any of the above parts are not installed properly,
excessive noise or vibration may be transmitted to the
vehicle body.
