Warning
• Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and
damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line
Safety Procedure”.
• Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and
damage. Fuel can also irritate skin and eyes. To prevent this, before performing the fuel pump unit
removal/installation, always complete the “Fuel Leak Inspection After Fuel Pump Unit
Installation”.
• A person charged with static electricity could cause a fire or explosion, resulting in death or
serious injury. Before draining fuel, make sure to discharge static electricity by touching the
vehicle body.
Caution
• Because the fuel tank is constructed such that the fuel level is higher than the installation surface
of the fuel pump, fuel leakage could occur. If the fuel gauge indicates a fuel level of half or more,
perform the following Steps 1-6 to drain approx. 10 L {11 US gal, 8.8 lmp gal} of fuel.
• Disconnecting/connecting the quick release connector without cleaning it may possibly cause
damage to the fuel pipe and quick release connector. Always clean the quick release connector
joint area before disconnecting/connecting using a cloth or soft brush, and make sure that it is
free of foreign material.
• To prevent the SST from coming off the fuel pump cap while performing the work, always perform
the removal/installation procedure with 2 people. One person presses the SST against cap from
directly above, while the other person rotates the SST.
