I should add that progress will be slow for a bit. It's winter, and I do not yet have access to a heated shop, so this work is preliminary.
One reason it needs it is that, like many farm trucks, it gets driven only occasionally, and usually it sits long enough that it won't start. So I want to get it running, but also wire it for an easy-connect trickle charger and maybe an easy way to prime it and get fuel flowing.
Any suggestions along these lines are much appreciated.
