Disconnect fuel supply hose quick-connector.
☞ Make sure of fuel leak after disconnecting fuel hose quick-connector and an inrush of foreign substances.
When removing the part of high pressure fuel system, wait for 30~60 seconds and check the pressure relief then proceed your job.
And make sure to wear your protective glasses while you are working and keep cleaning your surroundings.
Foreign material may cause other problem in fuel system.
For the exact test fuel system install the CRT-1000 and diagnose vehicle.
IG KEY "OFF" , ENGINE "OFF"
Remove air cleaner assembly.
Disconnect fuel supply hose quick-connector.
☞ Make sure of fuel leak after disconnecting fuel hose quick-connector and an inrush of foreign substances.
Install low fuel pressure gauge between fuel supply hose quick-connectors.
- Use the low fuel pressure gauge (CRT - 1051), gauge connection tube (CRT - 1052) and connection adaptor (CRT - 1053).
Assemble air cleaner assembly.
Remove tubes (rail to injector).
- Remove tubes after cleaning fitting part for blocking inflow of foreign substances.
Use dust caps (CRT - 1035) for blocking inflow of foreign substances.
Install regulator valve (CRT - 1020) and three plug 12 mm to nipple of common rail.
■ Tightening torque : 2.5~2.9Kgf.m
Install flask & holder (CRT - 1030), visible tube (CRT - 1031) to regulator valve (CRT - 1020) and return nipple of rail pressure regulator.
Connect high pressure gauge (CRT - 1040) and adaptor connector (for Bosch, CRT - 1043) after disconnecting rail pressure sensor connector.
Disconnect all injector connectors and fuel pressure regulator connector.
Actuate rail pressure regulator.
☞ Supply battery power to fuel pressure regulator using PRV Control Cable (CRT - 1044)
☞ Do not exceed 60 seconds when actuating fuel pressure regulator. (Make sure not to increase temperature of fuel pressure regulator too much)
Fill fuel the low fuel pressure line after operating the priming pump of fuel filter.
Inspect rail pressure rising condition with engine cranking.
