The idea behind this test is to seal the system completely so coolant could only escape from places it shouldn't be able to escape from. ie. Loose clamps, worn hoses, etc. Your pressure relief cap should NOT BE ON THE TRUCK AT ALL DURING THIS TEST

That helps. When I first made the post in the first comments I said I was pressurizing it through the radiator hose and nobody corrected me on that. That’s my fault. So that’s how I did it the second time. I will correct it and run the pressure test again. Thank you
