When re-assembling, you need to pre-tighten the corners
and then tighten the 5 bolts. Otherwise, the uneven
compression of the sealing rubber ring of the fuel pump will
easily cause leakage and cause safety hazards.
Caution:
●Early production vehicles do not contain brackets ⑵ , you
can purchase and install them by yourself.
●The length of the bolt without bracket (1) is M6 ×16, and the
length with bracket is M6×20.
●The fuel pump is a precision component that needs to be
assembled in a dust-free workshop and requires rigorous
testing, so it is forbidden to disassemble it by yourself.
Therefore, the decomposition process of the fuel pump is not
explained here.
3.
Remove the oil level sensor
Place the removed fuel tank assembly. It is recommended
to protect the fuel pump at the bottom of the fuel tank.
Use a 10# sleeve to remove the 4 M6
×
16 bolts ⑴ , and
pull the sensor
⑵
out. Be careful not to pull it forcibly to
avoid the deformation of the float connecting rod, which will
cause the deviation of the oil volume display to increase.

4. Remove the external parts of the fuel tank
assembly.
a.Take off the 4 segments directly ⑴ .
b.Press down the fuel tank cap ⑵ and then rotate it
counterclockwise to remove it.
c. The battery rubber pad (3) is pasted on the shell of the
fuel tank, which is difficult to remove. If you need to remove
it, you can use a heat gun to heat it and tear it off, or use a
cleaning agent that removes the adhesive to remove it.
Examination
1. Fuel pressure test
Refer to the fuel pump section in the "Maintenance" chapter for the test method.
2. Fuel pump inspection
Unlock the vehicle, turn the engine stop switch to "", you should be able to hear the sound of the fuel pump running. If you
don't hear the fuel pump running sound, turn off the engine and turn off the power first.
Refer to the steps in the "Maintenance" chapter to replace the high-pressure oil pipe first to remove the surrounding bottom
plate. Refer to the previous fuel tank removal steps to unplug the fuel pump.
Use a multimeter to measure the voltage of the fuel pump plug cable end, unlock the vehicle, and when the engine stop
switch is turned to "", the fuel pump will accumulate pressure for about 5 seconds, during which time the battery voltage should
be able to be measured.
If the battery voltage can still be measured without starting the engine after the pressure accumulation is completed, check
whether the fuel pump relay is normal. If the relay is normal, the fuel pump needs to be replaced if it is abnormal.
3. Oil level sensor
Use the resistance file of a multimeter to measure the resistance. The lowest position (empty oil): 287
～
313Ω, the highest
position (full oil): 27
～
79Ω.
Pull the float connecting rod, there should be no jamming phenomenon and good contact of the contacts during the rotation
process.
Check the appearance of the float, and there should be no damage.
