Awright guys looking for a little assistance

My car broke down yesterday and after getting it home by recovery truck, we found that the fuel pump was sticking. After putting a direct 12 volt supply to it, the pump kicked back into life. The car is now starting no problem again, but dont to get caught out again, so want to replace it ASAP

Now its a small turbo ESCOS with stage 2 GGR chip, hybrid turbo, uprated fuel pressure regulator and pump, but the receipts I have dont actually list the spec of the pump

What pump do I need for the car, and wheres the best place to buy it from, and is it a drop the tank off number to replace it

Any advise would be appreciated
