Here's the directions for a gasoline job.
To protect the pump from damage caused by mineral
deposits or freezing, use PumpSaver to treat pump. This
prevents freeze damage and lubricates pistons and seals.
<SNIPPED FOR BREVITY>NOTE:
If PumpSaver is not available, draw RV antifreeze
(non-alcohol) into the pump by pouring the solution into a
3-foot section of garden hose connected to inlet adapter
and pulling recoil handle twice.
OK, how do you turn an electric model over about two revolutions???
