• As a guide, if the fuel tank is full the fuel leve
l reaches or is less than the level on the fuel gauge as
shown, when approximately 34 (9 US gal, 7 1/2 Imp gal) of fuel is drained from a full fuel tank.
3. Open the fuel filler cap to release the pressure inside the fuel tank.
4. Release fuel pressure from fuel line. Refer to EC-182, "Work Procedure"
(QR25DE), EC-687, "Work Pro-
cedure" (VQ35DE).
5. Remove rear seat cushion. Refer to SE-36, "Removal and Installation - Seat Assembly"
.
6. Turn the four retainers (A) 90 ° in a clockwise direction and
remove the fuel pump inspection hole cover.
7. Disconnect the fuel level sensor, fuel filter, and fuel pump assembly harness connector (C), EVAP hose quick connector
(A), and fuel feed hose (B) quick connector.
a. Disconnect the quick connectors as follows: • Hold the sides of the connector, push in tabs and pull out the
tube.
• If the connector and the tube are stuck together, push and pull
several times until they start to move. Then 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 the resin tube away from heat. Be especially careful
when welding near the tube.
• Prevent acid liquid such as battery elect rolyte, from getting on the resin tube.
• Do not bend or twist the tube during installation and removal.
• Only when the tube is replaced, remove the remaining retainer on the tube or fuel level sensor,
fuel filter, and fuel pump assembly.
• When the tube or fuel level sen sor, fuel filter, and fuel pump assembly is replaced, also replace
the retainer with a new one (green colored retainer).
• To keep the connecting portio n clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the c onditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interv iew to document the facts and conditions when the noise occurs and any
customer's comments; refer to GW-9, "Diagnostic Worksheet"
. This information is necessary to duplicate the
conditions that exist when the noise occurs.
• The customer may not be able to provide a detailed descr iption or the location of the noise. Attempt to obtain
all the facts and conditions that exist when the noise occurs (or does not occur).
• If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer is
concerned about. This can be accomplished by test driving the vehicle with the customer.
• After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
• Squeak —(Like tennis shoes on a clean floor) Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
• Creak—(Like walking on an old wooden floor) Creak characteristics include firm contact/slow mo vement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
• Rattle—(Like shaking a baby rattle) Rattle characteristics include the fast repeated contac t/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
• Knock —(Like a knock on a door) Knock characteristics include hollow sounding/someti mes repeating/often brought on by driver action.
• Tick—(Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loose components/can be caused by driver
action or road conditions.
• Thump—(Heavy, muffled knock noise)
Thump characteristics include softer k nock/dead sound often brought on by activity.
• Buzz—(Like a bumble bee) Buzz characteristics include high frequency rattle/firm contact.
• Often the degree of acceptable noise level will vary depending upon the person. A noise that you may judge
as acceptable may be very irritating to the customer.
• Weather conditions, especially humidity and temperature, may have a great effect on noise level.

< PRECAUTION >
PRECAUTIONS
Be certain that the gauge face indicates R-134a or 134a. Make sure
the gauge set has 1/2 ″-16 ACME threaded connections for service
hoses. Confirm the set has been used only with refrigerant HFC-
134a (R-134a) along with specified oil.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or aut omatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Do not attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC134a (R-134a) and specified
oils have been used with the scale. If the scale controls refrigerant
flow electronically, the hose fitting must be 1/2”-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder's top valve
when filling the cylinder with refrigerant. Also, the accu racy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
