Hi, I have a 2007 3.2 ml triton. I was wondering if anyone could tell me if i remove the fuel lines and rail to take the intake manifold off [as i need to clean the carbon build up] do i need to bleed the fuel lines when i reinstall. i have been told that the pressure in a common rail system is very high and can damage things by trying to bleed air out. I also need to adjust the valve lash while i have it down. Any help would be greatly appreciated.

Any work on a common rail diesel should be done with the knowledge, the high pressure if still present in the rail, can cause life threatening velocity diesel spray when a union is undone/loosened. If any spray happens and it hits you it most likely will enter the blood stream causing blood poisoning, irreversible. Death is always later. 20,000psi cuts flesh rather
well. 2000psi of a conventional diesel kills if it hits you.
With suitable precautions the system can be undone safely and repairs and adjustments made.
The integrity of the replaced connections is very important to ensure no leaks or the High pressure diesel. Never crack any injector line if running or shortly after running.
The injectors are electronic and system pressure will quickly force air out when the high pressure pump begins to supply.
This is only general info. You need to determine specific safety procedures before doing the work.

Thanks
Ross, where could i find out the applicable safety procedures? I am quite familiar with the old school of diesels but do not know much about this newer type of fuel systems, been a long time out of the trade.

azzman : I have just removed my fuel lines , did not have any such problems as mentioned , when it comes to restart / bleeding these motors are dead easy , just pump the plunger at the fuel filter till it goes hard , you don't need to undo anything except maybe the bleeder on the filter housing but that's more for the filter change , kick it in the guts .... :-) PS the fuel line can only be remove a number ??? of times .
As for the high pressure, didn't know about this, had no problem , read & asked a lot on newtriton
forum ???? , so you could have a look there too or the pajero
forum.
Cleaning out the carbon by removing the manifold i think would be best option , i gave the spray a go :-( So this is what i did ..... good luck with yours .... cheers

Thanks Nick B, i have been told that you need to let the motor sit stopped for a while to allow the high pressure side of the fuel system to bleed down before you crack any lines. Did you do that or just into it?
