Hi does anyone know if the diesel lift pump in the diesel 5th gen is different to the petrol 5th?

Chrysler Grand Voyager 25th anniversary

So was going to change the diesel lift pump the one that sits on top/in the fuel tank it appears to be getting  noisy, and when I approached Jeep dealer they said its £600!!

As the Petrol 3.3,3.6 and 4.0 are around £50-120 on Rock auto so even with shipping and tax no where near £60 I wonder if I could replace mine with one from say a 4.0 litre

£600 for a plastic pump really  could understand a high pressure one costing that much

part number 04809932AA Maybe someone techy can explain why there is such a difference in price.
