couple of suggestions...

install a short electrical lead at the pump so you can run a dedicated generator ...even if you need to borrow one daily...

depending on the well casing diameter and type of pump installed (foot valve, submersible, injection,... have different applications), you might be able to use a gasoline pump (some have 160'+ head values) where an additional drop tube (side by side), or plumb a "T" and couple of ball valves on the current drop tube so a gasoline driven pump can be substituted for the electric one...some one with more practical knowledge of pumps may know, possible even a 5/8" or 7/8" garden hose for a drop tube

before I capped my shallow water well(which has a foot check valve), I could lift and lower my PVC drop tube and pump water...
