Toyota Yaris: Fuel Pump / Removal

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 (-) auxiliary battery terminal.
• Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

NOTICE:

• After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 120 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.
• This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.

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.

NOTICE:

• Do not use any tools other than specified in this operation as this may result in damage to the fuel pump gauge retainer or 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.
