i had a slight leak from the pump gaskets w/ very good oil press so i then decided to change the gaskets. all put back together and no oil press at all so i took it a part again to double check and it looks good. i start the car again and still no oil press??? the car ran for about a min w/ no press, do i really need to prime it.. would idle not be good enough? it has a spacer but not the bigger gears for the HV pump.. thanks
