I started it up and now only 3 days and it lost prime.
Turned off ignition and turned it on and it took about 20 seconds to get oil pressure.
I did use the oil accumulator and got 25 psi shot into the motor.
But oil pressure did not go up quick enough for my liking.
Wondering if they make a 1 way check valve for the bottom oil line?
Going to try again tomorrow and if I lose prime again I'm going to change out the oil filter back to my trusty WIX.


Sammy, mine does the same with the Wix and Mobil1 filters, and mine does what yours does, exactly. I am now thinking the filter is full, but the oil in the pump drains back into the engine and loses its prime. In the summer heat, I sometimes get pressure right away.

I am thinking if there is a way to prime the engine with the accumulator off of the front of the oil pump...maybe that would work???

Mark. my oil accumulator sandwich is between the pump and oil filter. When I hit the switch, I'm sure that oil must go into the line I'm going to see if I can raise the rear oil line above the oil pump tomorrow, somehow. I might have to change a fitting or 2 to get the line up. I hate seeing no oil pressure for 20-25 seconds. Never had this problem before.
