Is their a part # for JUST the electric fuel pump motor??? Without having to buy the complete assembly? Id like to carry one as a spare, but I don't want to deal with the huge fuel pump assembly. I know a Disco 1 aftermarket pump can be had for $14 on feebay, anyone find something similar for the Disco 2?

 

Away from original, there is a few brands as Carter, Airtex aftermarket.

I installed those in other cars externally and have had decent results. My obsession was to eliminate a pump being inside the tank to have it serviceable/replaceable in minutes with no need to remove/dig into the tank.
Did an extensive study about pressures and volumes and chose those. Mounted/held in-line by the chassis wrapped in foam, lower than the minimum fuel level, with pre-filter and a big sock at the suction point. The modification took a lot of adrenaline but has paid a couple of times. Open access for checking, wiring, testing. Can be messy and needs tight fittings. I even installed a led indicator at the pump terminals to confirm power is reaching pump.
Not an adventure for everyone, but worked for me. And there is a spare in my trunk, about 6 " x 2 "
