Precautions on Fuel System Service

WARNING
!
• Before attempting service of any type on fuel system, the following should be always observed in
order to reduce the risk of fire and personal injury.
– Disconnect negative (–) cable at battery.
– Do not smoke, and place no smoking signs near work area.
– Be sure to have CO
– Be sure to perform work in a well-ventilated area and away from any open flames (such as gas hot
heater).
– Wear safety glasses.
– To relieve fuel vapor pressure in fuel tank, remove fuel filler cap from fuel filler neck and then
reinstall it.
– As fuel feed line is still under high fuel pressure even after engine was stopped, loosening or
disconnecting fuel feed line directly may cause dangerous spout of fuel to occur where loosened
or disconnected. Before loosening or disconnecting fuel high presser line, make sure to relieve
fuel pressure referring to "Fuel Pressure Relief Procedure: For Diesel Engine Model".
– A small amount of fuel may be released after the fuel line is disconnected. In order to reduce the
chance of personal injury, cover the fitting to be disconnected with a lint-free cloth. Be sure to put
that cloth in an approved container when disconnection is completed.
– When connecting fuel pipe flare nut, first tighten flare nut by hand and then tighten it to specified
torque.
– The system can inject the diesel fuel into the engine at a pressure up to 160,000 kPa (1,600 kg/
cm 2 , 22,760 psi). Before carrying out any work, check that the injector rail is not under pressure
and that the fuel temperature is not too high.
– Do not place your hand near to a leak on the high pressure fuel circuit.
– Do not run engine with disconnecting fuel pipe and/or removing fuel system components.
– Do not expose removed fuel system parts to dust. Keep always clean.
– When servicing the fuel tank, it should be treated with respect, with no contact with sharp edges
or hot surfaces. In addition, the fuel tank should not be dropped since fuel tank, fuel pump and
other components can be damaged by the impact. If dropped, all components should be replaced
because there is a risk of damage.
– Note that fuel hose connection varies with each type of pipe. Be sure to connect and clamp each
hose correctly referring to "Fuel Hose Disconnecting and Reconnecting: For Diesel Engine
Model".
After connecting, mark sure that it has no twist or kink.
• Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep
sparks and flames away from fuel. Fuel line spills and leaks are dangerous. Fuel can ignite and
cause serious injuries or death and damage.
