After getting my engine on the run stand and letting it sit a few days between starts, it does seem that it takes 4-5 seconds before it picks up oil pressure so I decided to put in a check valve. Could you guys take a look and see if what I have mocked will work or do I need to take another approach. I thought I remember reading in my other post, that it was beneficial to have it laying horizontal, just worried about the two 90 degree bends.
