1071 220D lift pump more info

I now have fixed the leak on the lift pump - I found that the temporary o ring my friend installed was ok but did not stop the leak completely - eventually got a new o ring from MB dealer - the part number is:

005-997-47-45 it is a VE seal ring which I guess is somewhat different to a regular o ring you get elsewhere. Removed the banjo fitting and then remove the lower fitting which screws into the pump itself - inside you will find the o ring sits in a groove near the top - remove and clean out the old o ring and install - I just tightened down firmly - put banjo fitting on with new copper crush washers and tightened down firmly - so far not a drip from it!

Its pretty tight in there but with the help of a stubby adjustable wrench was able to get job done with only one bleeding finger - you might find a crows foot wrench (bottom fitting is 22mm) a lot easier.
