Components Of Low Pressure Transfer Line; Fuel Tank; Fuel Filter - SSANGYONG 2004 Rexton 2.7XDi Workshop Manual

Components of Low Pressure Transfer Line

Low pressure stage is to supply sufficient fuel to high pressure section and components are as below.
• Fuel tank (including strainer)
• Hand priming pump

• Fuel filter

• Transfer pump
• Other low pressure fuel hoses

Fuel tank

Fuel tank is made of anti-corrosion material and its allowable
pressure is 2 times of operating pressure (more than 0.3 bar).
It has protective cap and safety valve to prevent excessive
pressure building. Also, it has structure to prevent fuel from
leaking in shocks, slopes and corners and to supply fuel
smoothly.
Priming pump
If fuel runs out during driving or air gets into fuel line after fuel
filter replacement, it may cause poor engine starting or dam-
age to each component. Therefore, the hand priming pump is
installed to bleed air from transfer line.
When the vehicle is under the conditions as below, press the
priming pump until it becomes rigid before starting the engine.
- After run out of fuel
- After draining the water from fuel filter
- After replacing the fuel filter
Press the priming pump until it becomes rigid before starting
the engine.
Fuel filter
It requires more purified fuel supply than conventional diesel
engine. If there are foreign materials in the fuel, fuel system
including pump components, delivery valve and injector nozzles
may be damaged.
Fuel filter purifies fuel before it reaches to high pressure pump
to help proper operations in high pressure pump. And more, it
separates water from fuel to prevent water from getting into
FIE system (high pressure line).
