Or.................
Recently my mates sierra estate twin cam keep blowing fuel pumps we actually had to change 2 full sender and pump units , then on the 3rd time we couldn't get one .
After having taken it in and out the tank a few times, we realised that it looked the same as mk3 fiestas and mk5 escort pumps.

So we had the whole unit out of the tank pulled the pump off the bracket carefully you have to bend a tag out the way that supports it then unclipped the wiring .
We then put a mk3 fiesta SI pump back in
( we crossed referenced part numbers and they were the same )

What I'm trying to get at is that people put escort Cossie pumps in fiesta turbos .
So surely what we have done can be done with a escort Cossie pump.
Meaning that you ain't gotta change the tank/lines/filters add a swirl pot.
