pull the rubber wheel arch lining down on the drivers side and look through the gap between the chassis and the body you will see the makers plate on the side of the pump.
I also think that if it has the hitachi type maffs sensor it has a zexel pump and injectors and if it has a bosch maffs it will be bosch pump and injectors. I dont know this for certain but this has been the case on 3 vehicles that i have bought injetion parts for.
