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 gauge sender sub-
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. 10-15 L {11-15 US gal, 8.8-13 
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.
