Removal
1. | Release the residual pressure in fuel line (Refer to “Release Residual Pressure in Fuel Line” in this group).
2. | Remove the rear seat [LH] (Refer to “Seat” in BD group).
3. | Remove the fuel pump service cover (A).
4. | Disconnect the fuel pump connector (A).
5. | Disconnect the fuel feed tube quick connector (B).
6. | Disconnect the fuel tank pressure sensor connector (C).
7. | Disconnect the vapor tube quick-connector (D).
8. | Remove the plate cover (E) after removing the installation bolts, and then remove the fuel pump from the fuel tank.
Installation
1. | Installation is reverse of removal.
Fuel pump plate cover installation bolt : 1.96 ~ 2.94 N.m (0.2 ~ 0.3 kgf.m, 1.44 ~ 2.17 lb-ft)
Be careful of fuel pump direction when installing.
Inspection
[Fuel pump]
1. | Turn ignition switch OFF and disconnect the negative (-)battery cable.
2. | Remove the fuel pump assembly.
3. | Check motor operation by fuel pump connector (A) connecting power(No.2) and ground(No.4)
Pin No. | discription
1 | Fuel sender signal
2 | Fuel pump (+)
3 | Fuel sender ground
4 | Fuel pump (-)
[Fuel sender]
1. | Using an ohmmeter, measure the resistance between terminals 1 and 3 of sender connector (A) at each float level.
Pin No. | discription
1 | Fuel sender signal
2 | Fuel pump (+)
3 | Fuel sender ground
4 | Fuel pump (-)
2. | Also check that the resistance changes smoothly when the float is moved from "E" to "F".
Position | Resistance (Ω) | Capacity (ℓ)
E | 197 ~ 203 | 3.0
1/2 | 64.2 ~ 68.2 | 24.6
F | 6 ~ 10 | 49
