Inspection
1. Front seat (driver's side) - Remove
2. Rear Heater Duct (Left Side) - Remove
3. Access Panel - Remove
- Remove the access panel (A) from the floor.
4. Breather Line and Suction Line - Inspect
- Disconnect the quick-connect fitting (A) from the fuel tank unit, and
connect a
vacuum pump/gauge, 0-30 inHg, to the fuel tank unit as shown
- Start the engine, and check the vacuum.
- If there is vacuum, go to step 3.
- If there is no vacuum, replace the fuel filter - Refer to: Fuel Tank
Unit Disassembly and Reassembly (2WD), or Fuel Tank Unit Disassembly and
Reassembly (AWD).
- Turn the vehicle to the OFF (LOCK) mode
- Connect a vacuum pump/gauge, 0-30 inHg, to the suction line (A) with the
joint in the fuel pressure gauge set, and apply vacuum to the line.
- Raise the vehicle on the lift.
- Remove the front center member.
- Disconnect the quick-connect fitting (A) from breather line, then plug
the
suction line with the joint in the fuel pressure gauge set and a rubber cap
(B).
- Lower the vehicle
- Connect a vacuum pump/gauge, 0-30 inHg, to the suction line (A) with the
joint in the
fuel pressure gauge set, and apply vacuum to the line.
- If the line holds vacuum, check for a blockage in the breather line
between the fuel tank and the suction joint. If there is blockage,
replace the fuel tank - Refer to: Fuel Tank Removal and Installation
(AWD), or Fuel Tank Removal and Installation (KA/KC).
- If the line does not hold vacuum, go to next step.
- Raise the vehicle on the lift.
- Connect a vacuum pump/gauge, 0-30 inHg, to the fuel fill pipe side
breather line (A), and apply air pressure to the line.
- If the air pressure holds, or a blockage between the suction line
and
the fuel fill neck on the breather pipe, and replace the part that is
causing the blockage.
- If the air pressure does not hold, go to next step.
NOTE: When check for the one way valve tube (B), remove it, then
connect
a vacuum pump/gauge, 0-30 inHg, with the joint in the fuel pressure gauge
set, and apply vacuum or air pressure by one direction to the valve as
shown.
- Remove the joint and the rubber cap (C) from the suction line (D), and
reconnect the quick-connect fitting.
- Install the front center member.
- Lower the vehicle.
- Connect a vacuum pump/gauge, 0-30 inHg, to the suction line (A) with
the joint in the fuel pressure gauge set, and apply pressure to the line.
- If the air pressure holds, the breather line and the suction line
are
OK.
- If the air pressure does not hold, check for a vacuum leak in the
suction line, and replace the suction line if needed.
- Reconnect the quick-connect fitting (B).
5. Access Panel - Install
- Install the access panel (A).
6. Rear Heater Duct (Left Side) - Install
