The “what to do” about a safety cutoff is what has kept me from already installing the pump you recommend.
I like making little reliability improvements, without introducing new failure points, or some gadget that would be hard to source if a guy was away from home and had to find something off the shelf.
Your electric pump is nice in that it doesn’t introduce the need for an external regulator (new failure point). It’s also cheap enough that you could easily throw a spare in the glovebox.
I like the simplicity of the mechanical pump. But I think the failures are more common than successes with the modern ones. Even if mine is working great now, where does my next replacement come from? (The Then and Now rebuild kits are probably the best option).
Inertia switches look goofy to me, even though I know nothing about the actual failure rate. The oil pressure switch is probably better, but those are certainly just as offshore and sketchy as any other part these days.
We have various kinds of “dead man switches” in my workplace that are safety interlocks requiring a person to be standing in a certain place, touching a certain button to ensure hands are not in equipment, etc. Something along those lines might be the ticket. Worthy of more consideration.
