Fuel assembly as expected is NOT covered in New Zealand so I will be replacing the pumps myself sometime. I will get a new lock ring as they are cheap. Might as well leave the sender side alone as it is fine.

My questions are
- What you would recommend to replace?
- Has anyone done this in the last couple of years and NOT had the leak return? ie have they finally designed/made the parts well enough to actually fix the problem?
My car only has 26,000 miles so I don't want to replace unnecessary items but my E55 repair fund is pretty healthy so I will do whatever needs to be done.


Left side looks great



Right side, not so much



It seems to be leaking from below the fuel pump electrical connection. Is there a gasket here or should I be replacing the whole white pump assembly?
I fixed it.
