This is my first post. I've found this site really useful so far.
I'm trying to replace the fuel filter on my W210 '02 Reg Diesel Automatic. I've read that to depressurise the fuel filter I need to run the engine then while its on remove the fuse to the fuel pump - this should cut out the engine once there's no more fuel in the filter. I've done this, but the engine just keeps running - even after several minutes there's no sign of the engine cutting out. (The fuse is the 25Amp one in slot 6 in the fuse box under the rear seat as per the MB list).
Am I going about this correctly, or am I missing something?
Also, once I get past this holdup (help please:? and have replaced the filter, I believe this model's fuel system is self-bleeding. I'll fill the fuel filter canister with fuel before refitting the fuel lines, but is there anything else I need to do to prevent air getting into the fuel system? I've read other posts, eg links to the tech diagrams on detali.ru, and can't find any sight of a primer pump in the engine.
Any help/info will be appreciated.
