There you go!!!  You shouldn't loose prime for a while now

I have a bit of concern using spin-on cartridges on the suction side of the pump.
Seems the slightest bit of clogging (or polymerized WVO) would seriously restrict the flow however, your real world application may prove otherwise.
Do you have the space and available connection points to rig up a post-pump filter ?

Reference Primes:
"The use of electronic computers has accelerated the discoveries and found all records since 1951. The record passed one million digits in 1999, earning a $50,000 prize. In 2008 the record passed ten million digits, earning a $100,000 prize. Additional prizes are being offered for the first prime number found with at least one hundred million digits and the first with at least one billion digits.

Rank Prime number Found by Found date Comments
1st 243,112,609 − 1 on 23 August 2008 This number is 12,978,189 digits long. It is the largest of the 47 known Mersenne primes as of June 2009.

So does this mean if my engine runs about 13 million times 2 days that it will loose prime?

Reference pump seals:
You know I didnt remove the very bottom pipe fitting next to crank case drain where it pulls oil up the tube. I didnt know there might be another ball bearing with a spring down there. I will remove that plumbing and check. Thank you.

Found these low / high oil level switches in my reading:

And I have several Murphy switches, top quality for money, for $92 I am thinking about this:

I've seen many of those Kenco switches (and others like them) in service over the years. They are very reliable, and in general, maintenance free. I've seen them in service on turbines, electric motors, pumps, air blowers, compressors, etc., from 3 to 15,000 HP. They are often used for emergency shutdowns.

I use this Murphy oil level switch and can confirm it works quite well.  If you set it up properly, one can use the high level float to shutdown in the event of a broken oil dipper.  The oil level is lower when the engine is running and the oil dipper is splashing oil than when the engine is not running or the oil dipper is broken.  The high level float will also detect a coolant or fuel leak into the crankcase.  Of course, the low level float provides the normally expected low oil level shutdown protection.  Just be mindful that you have to vent this Murphy switch to the crankcase for it to function properly.
