You likely don't NEED a regulator as it will never pull enough to hurt anything. Just my .02 I heard that anything over 12in/Hg was too much on a wet sump. I had to adjust mine to get under that using a 4 vane Moroso BTW. I've seen folk mount the reg on the opposite rocker cover to the take off, this way there is an air flow through the engine and you will pull oil through.
