That might be a possibility. With the fuel pump you have the white harness plastic that goes around it with the cell in the middle. With our cars there are 2 different versions and this is where I have ran into problems.
The fuel harness in the newer P1 platforms will have 3 holes at the bottom where as the older one will only have 2. The uprated fuel cell I have is for the older platform and wont fit into my current harness so hoping to get an older one for that fuel cell to be fitted and mapped to the car.
so its more just the white casing im after. something like this in the link below:
