Your Mercedes
W123 230e
Newbie forum visitor. Have read some stuff before but now need to ask a question.
Need to open my fuel level sensor and after reading up it seems I need one of these massive 46m (1 13/16) sockets.

The ones the sell 'off the shelve' are all quite massive. So the question is: would the 'Mercedes Adblue' socket work for this?
It appears to be the right size and from what I can see it's not too deep, which may actually help.
Anyone have a view?
