WARNING:
Read “General Precautions” when wo rking on the fuel system. Refer to FL-3, "
General Precaution".
1. Check fuel level on fuel gauge. If fuel gauge indicates more than the level as shown in the figure (full or almost full), drain fuel
from fuel tank until fuel gauge indicates level as shown in the fig-
ure or below.
NOTE:
Because fuel will be spilled when removing main and sub fuel
level sensor units for the top of the fuel is above the main and
sub fuel level sensor units installation surface.
• As a guide, fuel level becomes the position as shown in the
figure or below when approximately 20 (5-1/4 US gal, 4-3/8
Imp gal) of fuel are drained from fuel tank.
 In a case that fuel pump does not operate, perform the follow-
ing procedure.
a. Insert hose of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to draw
fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-10, "
Component".
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel from fuel tank.

665, "Fuel Pressure Check" (VK45DE).
3. Open fuel filler lid.
4. Open filler cap and release the pressure inside fuel tank.
5. Remove rear seat cushion. Refer to SE-95, "
Removal and Installation".
6. Peel off floor carpet, then remove inspection hole cover for main and sub fuel level sensor units by turning clips clockwise by 90
degrees.
7. Disconnect harness connector and fuel feed tube.
Disconnect quick connector as follows: Hold the sides of connector, push in tabs and pull out tube.
 If quick connector sticks to tube of main fuel level sensor unit, push and pull quick connector several times until they start to

 Do not bend or twist resin tube during installation and
disconnection.
 Do not remove the remaining retainer on hard tube (or the equivalent) except when resin tube or retainer is
replaced.
 When resin tube or hard tube (or the equivalent) is replaced, also replace retainer with new one.
 To keep the connecting porti on clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
8. Remove main fuel level sensor unit, fuel filter and fuel pump assembly, and sub fuel level sensor unit as
follows:
CAUTION:
 Do not bend float arm during removal.
 Avoid impacts such as fallin g when handling components.
a. Removal of main fuel level sensor uni t, fuel filter and fuel pump assembly:
i. Remove retainer.
ii. Raise main fuel level sensor unit, fuel filter and fuel pump assembly, and using snap ring pliers, remove fuel hose connec-
tor.
CAUTION:
Be careful not to damage fu el hose connector by expanding
them excessively.
b. Removal of sub fuel level sensor unit:
i. Remove retainer.
ii. Raise and release sub fuel level sensor unit to remove.
