Yup, new one installed. I went for the OEM a VDO (Siemens) but ordered it through an Ebay seller who drop shipped from Adelaide. Turns out it is exactly the same unit as what was in the car but the new one has the name FoMoCo and Siemens ground off for some reason. Paid $384. My Mondy has been resurrected and purrs again
One problem I did have is on my first fill at the bowser I had a significant fuel leakage. Seems to be related to something at the top of the tank as it's not leaking now. After the pump clicked once I waited a few seconds and continued filling (as I usually do) it then kept going for another 10 litres or so which baffled me as the fill then went up to 68 litres and the tank was showing ¼ full when I pulled in to the station. I was trying to work out how this could be and wasn't smart enough to stop filling at around 50 litres. When I got in the car I smelled petrol and so got out and checked at the back of the car. It was raining, with water everywhere but checking the ground revealed there was petrol there - I'm guessing at least 5l must have spilled, maybe 10 even. So I let the station attendant know there had been a spill and gingerly drove off. So, since then there is no leak, none now so I'm thinking it's something at the top of the tank which is odd because I know I checked the tightness of the pump retaining ring and the connections. I haven't refilled the tank, I'm waiting till it runs down to about ¼ again and I'll have to drop the tank and re-check everything. Still a bit mystified. Wondering if it's possible that I'm getting a back-feed out of the top of the tank into the evap canister and out through the breather on that - I have no idea how that canister works but wondering if in draining the tank I damaged a seal in it. The other possibility is the seal around the pump being damaged, it looked in good condition and a new one doesn't come with the pump so I didn't bother changing it (new one from Ford is $210 or from Ebay $180). I think what I'll do first is drop the tank, fill it with 20l or so of petrol and tip it on its front edge so the pump is covered and will show if there is a leak around the pump. If not, will scratch my head and try and think what to do next.

I read somewhere in all my searching that the fuel pump in the Mondeo petrol models is considered a non serviceable item, designed to last the lifetime of the vehicle. Given that the filter is integral to the pump they consider the filter should never need to be changed. My pump still worked fine, just like others who have had this issue it's just the connection on the top of the pump that fails. The condition of my filter was pristine as well, no signs of clogging or debris in it at all so I'm guessing they're correct in that aspect. Shame they didn't design the electrical connector very well though. It's be worth you dropping the tank at 70-80,000kms as you suggest and just unplug the connector at the top of the fuel pump and have a good close look for any signs of arcing on the pump power pins.
Here's a pic of mine:
