CDI Fuel Leak
Hey all, I have a 2005 E320 CDI with a fuel leak in the vicinity of the high pressure fuel pump (right now I think it's just some bad fuel lines, not the pump itself, fingers crossed). Can I just disconnect and swap in some new fuel lines, or are they pressurized even when the car is off?

Are you talking around the injectors, the injectors have rubber hose connecting to each for the return, the return is rubber/braided line, i believe go to the pump.
on the common rail diesel, theres a steel fuel rail that connects to the injectors, you dont normally replace the steel lines.
I have the 06 E320 CDI, i recently smelled fuel leak, my #1 injector was seeping fuel around the injector seal.
