(6) Check the connection state of the fuel pump harness.
Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| Fuel pump body - Ground terminal of the fuel pump harness | Always | Below 50 Ω |
If the result is not as specified, reconnect the fuel pump harness to the fuel pump so that the ground terminal of the fuel pump harness is securely connected to the fuel pump body.
(7) Engage the 4 claws to install the fuel suction plate sub-assembly to the fuel sub-tank sub-assembly.
(8) Align the protrusion of the fuel sub-tank sub-assembly with the installation hole of the fuel suction plate sub-assembly and then slide the fuel suction plate sub-assembly to install the fuel sub-tank sub-assembly.

(10) Engage the clamp to connect the fuel pump harness to the fuel suction plate sub-assembly.
NOTICE:
- Do not damage the wire harness.
- When engaging each wire harness to the clamp, engage one wire at a time.
