It would work, but you'd have to pull the front end to change the pump, and trying to drive a D2 with no power steering in traffic is not going to be easy. At that point, just get a tow truck
The running the battery flat example I have seen killed its fuel pump as the voltage was dropping, which is about the worst electrical doodad to change in the whole car! I'm sure something else failed as well, but can't remember what.
A flatbed is looking like the best option tbh.
