L2250 Injection pump assembly cross reference

L2250- Injection pump swap out for D1302 engine

Does anyone know if the injection pump from a d1102 will work on a d1302?
the asembly bolts on, the main difference I see is the fuel pump iappears to be integrated into the 1102 assembly where the d1302 has a separate fuel pump? missing the assembly on a l2250 and want to take the assembly off a l2050 any suggestions?

Although the injection pumps are different I think perhaps I can use the injection pump off the L2050 on the L2250- it appears that the L2050 has the fuel pump integrated in to the injection pump while My L2250 has separate fuel pump from the injection pump.
My thought was to use the integrated pump and By pass the separate pump completely. Any thoughts anyone?
also how easy and pricey is it to find a replacement bucket for the bf400g loader?

Thanks for any input for a newbie
