It's a Ford Focus engine but unless they changed something, it's not a Ford Focus pump.
I think it's the pump shown in the link I posted earlier but maybe they changed when they went from the Silvertop Zetec engine to the Blacktop Zetec engine.
If you have exhausted all the fault finding options and you "know" the pump is faulty, you need to start looking at how you will get the tank out.
When you have the tank out, you will be able to correctly identify the pump with Glencoe or some other supplier.
