I got two pumps from the Corvair Ranch, they work, but I have to prime the carbs to get them to build up enough pressure to work. So the electric ones probably will be the long-term solution. And it looks like I've dropped a valve seat so it's not going anywhere until that gets fixed anyway.

Try the electric one and see how that works, until the parts come in for the original one.

Electric all the way. Easier and faster to repair you can one anywhere nothing special .
