Fuel Tank Removal
Special note: When maintenance of the fuel supply
system requires removal of the fuel line, the pressure
of the fuel system should first be released, so as to
avoid the spraying of high-pressure fuel.
1. Pull out the electrical connector of the fuel pump on the
top of the fuel tank.
2. Pull out the quick connectors of fuel filler hose II and
the inlet rigid pipe, as well as desorption hose I and
the desorption rigid pipe. Afterwards, use a cotton cloth
to block the mouthpiece to avoid the spraying of high-
pressure fuel.
3. Remove the fuel filler pipe connecting hose, air pipe,
and air return hose (two attachment clips and one
clamp) at the rear of the fuel tank.
4. Use specified torque of 26±3 N·m to remove the four
bolts and the strengthening cushion.
Fuel Pump and Charcoal Canister Removal
1. Assembly removal
(a) Remove the pipeline connected to the fuel pump.
(b) Clean any accumulated dirt from the flange of the fuel
pump.
(c) Starting diagonally, use a wrench to successively
remove the small bolts on the install panel of the fuel
pump in diagnostic mode.
(d) Pay careful attention not to damage the fuel level
sensor when taking the assembly out from the fuel
tank.
2. Assembly installation
(a) Carefully install the fuel pump and charcoal canister
assembly, as well as the oil level sensor, ensuring they
will not be damaged.
(b) Ensure that the port of the pipeline between the fuel
pump and charcoal canister is correct.
(c) Install the weatherstrip and install panel using specified
torque of 3-4 N·m to tighten the bolts.
Fuel Filter Removal
1. Pull out the two quick connectors which connect to the
fuel filter.
2. Loosen the bolts on the fuel filter mounting bracket in
order to take out the filter. The entire filter should be
replaced.
