What filter should be used? The old filter that came with the adapter plate has a tiny return oil hole in it and doesn’t seem like it would have enough flow. The numbers have been rubbed off so Napa can’t cross reference it. Will any same thread/gasket filter do? I ran 3/16 pressure line to it and was told by engine shop to regulate it to about 15psi outlet pressure so head would still get adequate oil supplied to it.
