It's likely a Cole-Hersey part. I don't know the P/N, but it shouldn't be hard to find a normally open pressure switch with 1/8" NPT threads activating around 6psi.

It's not the engine so much as the application - a fail safe for de-energizing an electric fuel pump when the engine isn't running.

It may well be CH, but it's a bit more effort to make sure it's a two-bladed, sealed contact, NO, ignition protected, oil compatible, 6psi switch that is known to work and fit in the application.

That's worth something.

MMI has packaged it with the elbow you'll probably want. The fuel pump kit comes with that and a lot more, including well written instructions.

Emergency OPSS Bypass

I cut a little thin piece of metal maybe 1/4"X3/4" that I keep in a small plastic bag in my tool box on the boat.
If the OPSS ever packs in or I need to trouble shoot I can pull the push on fittings off the OPSS and insert the piece of metal between them, wrap it with a piece of tape and I'll be in business.
