Hello...another little update. I got the fuel tank back this week with a new MRA assembly and weld ring installed on it. The good news is that the EFI Hardware shop also upgraded the pump to a high flow Walbro unit, so i guess that's good.
Spent today installing the new bits onto the tank, including reusing the old MRA lid as a fuel fill breather connection. Plugged the new setup into the ECU to map it, test the pump and calibrate the sender. Good success, the pump runs and the fuel gauge is operating perfectly. Another tick off the list...

Tank is back...
