The pump swap is not going to work without a great deal of work I'm sorry to say.
I am counting to have some work to get it done

The immobilisers won't swap between pumps for starters and the Bosch pump requires it's own ECU to function. The Bosch is the AS3 model which is a semi-electronic pump which has electronic timing control. Your last picture shows the timing actuator.
Well there is no rule that the immobilizer needs to be fitted on the pump itself
i know that they are different so it will stay somewhere on the engine bay. (or bypassed it depends on the day that i've put that on)
about the timming control. i think my DW8 as it too... i will take a pic. it as a strange actuator on the back.
using a picture that u've posted:
mine as a actuator in the orange spot that is why i needed the diagrams to find out what is that.

I would suggest you use the old DW8 Lucas pump on the XUD but the problem is the donor engine you have is turbocharged and I believe the DW8 is normally aspirated. This means that if you used the Lucas pump on the XUD the timing would be wrong and the fuelling inadequate on boost.
my DW8 pump is unusable. it is normal aspirated.

If you want to use the Bosch pump you will need to use it with an ECU designed for it as otherwise although the engine will run it will run badly due to the timing being stuck fully-retarded.
Wiring in the correct ECU is certainly possible and wiring diagrams can be made available to assist you. The ECU also controls the glow plugs and you'll also need the matching glow plug controller/relay.
I prefer to keep non ECU... less drama less wires... even then i have the ECU and wire harness from donor car.

Whatever, you'll be unable to use the immobiliser module on the Bosch pump and you must bypass it.
The alternative is to obtain a suitable Lucas pump from an early UK production Peugeot 306 D Turbo. It used the same XUD engine. You'll aso need the injectors and delivery pipes if you follow this route as the Lucas and Bosch items are not compatible.
I will try to find some other bosch pump... at the scrap yard. i would prefer to use a bosch.

The XUD engine pump cradle will accommodate both types of pump. There is a second set of tapped holes on the cradle flange face around 15 degrees away from the ones used by the Bosch Pump. Just undo the studs and screw them into the alternative holes.
found out that too here on the forum.

As you're planning to use a turbo engine have you given consideration to the need for an intercooler, different exhaust and totally different gearbox gear ratios?
Hope that helps a bit...
I know
intercooler is on the plans exhaust needs to be done, gear box will keep the DW8 one... it is a bit shorter but no trouble on that.
