I would install the anti drain back valve as close to the pickup as I could get it so it traps oil between it and the pump up
I haven't had any troubles with the dual line Milidon oil systems not making oil pressure after sitting in a long time(5+ motors) shruggy



Yes. Oil line loop up top . Old Milodon oil pump setups never ever gave me trouble till I bought their new oi l pump and cover. It's a year old. I cant do anything about it yet till I pull the motor. So I have to try and see if I can get this to work till the mean time.
Going to try the check valve like you said today.
