CAUTION:
-
Never perform work on fuel system components near any possible ignition sources.
-
Vaporized fuel could ignite, resulting in a serious accident.
-
Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.
-
Sparks could cause vaporized fuel to ignite, resulting in a serious accident.
HINT:
-
If a malfunction such as pump lock occurs and the fuel pump is damaged, excessive current may be continuously applied to the fuel pump control ECU, damaging its internal parts. Make sure to replace the fuel pump control ECU at the same time when replacing the fuel pump.
-
When the cable is disconnected / reconnected to the battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.
Learning completes when vehicle is driven

NOTICE:
-
Remove any foreign matter on the fuel tube joint before performing this work.
-
Do not scratch or allow any foreign matter to get on the parts when disconnecting them as the fuel tube connector has O-rings that seal the pipe (fuel pipe).
-
Be sure to disconnect the fuel tube joint by hand.
-
Do not bend, twist, pinch or kink the nylon tube.
-
Cover the disconnected fuel tube joint with a plastic bag to prevent damage and contamination.
-
If the fuel tube joint and fuel suction plate sub-assembly are stuck, push and pull to release them.
10. REMOVE FUEL PUMP GAUGE RETAINER
(a) Remove the fuel pump gauge retainer.
(1) Temporarily install SST (plate) and SST (claw) to the fuel pump gauge retainer.
SST: 09808-01071
SST: 09808-14031
09808-01030
09808-01090
HINT:
Securely insert the ends of SST (claw) into the insertion points in the fuel pump gauge retainer.

(4) Lightly press down on SST to prevent it from separating from the fuel pump gauge retainer. While pressing down on SST, rotate SST (handle) slowly to loosen the fuel pump gauge retainer.
NOTICE:
-
Do not use any tools other than specified as this may result in damage to fuel pump gauge retainer or the fuel tank assembly.
-
Do not press down on SST excessively as this may make the fuel pump gauge retainer hard to rotate, and may damage components.
-
Make sure to rotate SST (handle) horizontally. If it is rotated at an angle, SST may come off.
-
Do not spin SST too fast or use an impact wrench as this may result in damage to components.
-
If SST comes off of the fuel pump gauge retainer, loosen SST (bolt) and reinstall SST.
(5) While pressing down on the fuel suction tube with pump and gauge assembly, remove the fuel pump gauge retainer.
11. REMOVE FUEL SUCTION TUBE WITH PUMP AND GAUGE ASSEMBLY
(a) Remove the fuel suction tube with pump and gauge assembly from the fuel tank assembly.
NOTICE:
Be careful not to bend the arm of the fuel sender gauge assembly.
|
|
(b) Remove the fuel suction tube set gasket from the fuel tank assembly.
