High oil level switch

[Minggat]

After a lift pump failure that left my crankcase filled with fuel, I am interested in something that I saw years ago on a boat in La Paz. It was an system external of the crankcase, engine oil level switch. It was mounted in close proximity of the engine so it could actually tap into the crankcase and with the help of gravity, track the oil level. I think I remember it had a little canister and a window so you could see the oil level. At the time, I thought it was a little over the top. Now I am less judgmental.

I am basically looking for something to hopefully provide a pair of discreet switches. No amount of Googleing has helped so far.

Hi Minggat
"Murphy Switchgage" make em but they're expensive and take up a lot of space. You could fit one to a bulkhead and connect it with hydraulic hose to the sump. I've only used them for low lube oil level alarms not high level though.
