A nice added compliment/ safety item I have added to my oil system is a Stewart Warner SW76073 1/8” pipe switch.
It’s adjustable between 35 and about 42 lb and has normally open and closed terminals on it.

I wired in my stock idiot light to the normally open terminal so I know instantly if anything is wrong if the pressure drops below 35 lbs.

The normally closed terminal can be used for racing to kill the fuel pump by means of a relay, or kill the ignition ( without a relay) or with a relay kill both.

Yes, you need a override switch to get the motor started.

It’s very cheap insurance for 40 bucks and some wiring time if you ask me.
