BEFORE REPAIR PROCEDUREA6E401201006203
Warning
•Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep
sparks and flames away from fuel.
•Fuel line spills and leads 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 following “Fuel
Line Safety Procedures”.
Fuel Line Safety Procedures
Note
•Fuel in the fuel system is under high pressure when the engine is not running.
1. Avoid fuel line spills and leaks by completing the following procedures.
(1) Remove the fuel-filler cap and release the pressure in the fuel tank.
(2) When disconnecting a fuel line hose, wrap a rag around it to protect against fuel leakage.
(3) Plug the hose after removal.
End Of Sie
AFTER REPAIR PROCEDUREA6E401201006204
Warning
•Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and
damage. When installing the fuel hose, observe “Fuel Hose Installation” described below.
Fuel Line Air Bleeding
Caution
•Continuously cranking the engine for over 30 s can damage the battery and the starter.
1. Continue cranking the engine for 30 s and stop for 5—10 s until the engine starts.
Fuel Hose Installation
1. Verify that there is no damage or deformation on the fuel hose and fuel pipe when installing.

FUEL TANK REMOVAL/INSTALLATIONA6E401242110201
Warning
•Repairing a fuel tank that has not been properly steam cleaned can be dangerous. Explosion or
fire may cause death or serious injury. Always properly steam clean a fuel tank before repairing it.
•Fuel line spills and leakage are dangerous. Fuel can also irritate skin and eyes. To prevent this, do
not damage the sealing surface of the fuel gauge sender unit when removing or installing.
Caution
•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.

COMMON RAIL INSPECTIONA6E401213015201
Caution
•Do not remove the fuel pressure sensor nor the fuel pressure limiter from the common rail. Since
fuel pressure in the common rail is extremely high, the fuel pressure sensor, fuel pressure limiter,
or the common rail can be damaged, leading to fuel leakage if any of them are removed.
1. Visually inspect the common rail for damage and cracks. Also verify that there is no extreme rust which will
cause fuel leakage.
•If either is observed, replace the common rail.
