WARNING:
Be sure to read “General Precautions” before working on the fuel system. Refer to FL-4, "
General Pre-
caution".
1. Check fuel level with the vehicle on a level surface. If the fuel
gauge indicates more than the level in the figure (full or almost
full), drain fuel from the fuel tank until the fuel gauge indicates
level as shown in the figure or below.
NOTE:
Fuel will be spilled when removing fuel pump assembly if fuel
level is above the fuel pump assembly installation surface.
 As a guide, fuel level is at the level as shown or below when
approximately 15 (3-1/4 Imp gal) of fuel is drained from fuel
tank.
 In case fuel pump does not operate, perform the following pro-
cedure.
a. Insert fuel tubing of less than 20 mm (0.79 in) in diameter into fuel filler tube through fuel filler opening to
drain fuel from fuel filler tube.

b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-10, "HR16DE, HR18DE".
c. Insert fuel tubing into fuel tank through fuel filler hose to drain fuel from fuel tank.
2. Release the fuel pressure from the fuel lines. Refer to EC-377, "
Inspection" (HR16DE with EURO-OBD),
EC-681, "
Inspection" (HR16DE without EURO-OBD), EC-1035, "Inspection" (MR18DE).
3. Open fuel filler lid.
4. Open fuel door and unscrew the fuel filler cap to release the pressure inside the fuel tank.
5. Remove rear seat bottom. Refer to SE-18, "
Removal and Installation".
6. Turn the four retainers 90° in a clockwise direction and remove the fuel pump inspection hole cover.
7. Disconnect electrical connector (A) and fuel feed hose quick
connector (B).
⇐ : Vehicle front
 Disconnect the quick connector using the following procedure.
- Hold the sides of the connector, push in tabs and pull out the
tube.
- If quick connector and tube on fuel pump assembly are stuck,
push and pull several times until they move. Disconnect them
by pulling.
CAUTION:
 The tube can be removed when the tabs are completely
depressed. Do not twist it more than necessary.
 Do not use any tools to remove the quick connector.
 Keep resin tube away from heat. Be especially careful
when welding near the resin tube.
 Prevent acid liquid such as battery electrolyte, from get-
ting on resin tube.
 Do not bend or twist resin tube during installation and removal.
 To keep the connecting portion clean, free of foreign
materials and to avoid damage, cover them completely
with plastic bags or something similar.
 Do not insert plug to prevent damage to O-ring in quick
connector.

ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range (A) shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
 Check engine oil for white turbidity or heavy contamination.
 If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
 Oil pan (upper and lower)
 Oil pan drain plug
 Oil pressure switch
 Oil level sensor
 Oil filter
 Intake valve timing control solenoid valve
 Front cover
 Mating surface between cylinder head and camshaft bracket
 Mating surface between cylinder block and cylinder head
 Mating surface between cylinder head and rocker cover
 Crankshaft oil seals (front and rear)
 Oil filter (for intake valve timing control)
OIL PRESSURE CHECK
WARNING:
 Be careful not to get burned, as engine oil may be hot.
 When checking engine oil pressure, shift position should be “Neutral”, and apply parking brake
securely.
1. Check engine oil level. Refer to LU-6, "
Inspection".
