I can't tell if the Acumalator line on yours is fed off of the pressure side from the oil pump or if it is being fed off of the pressure side going to the block I have a 3 quart Moroso with a similar remote oil filter likes yours and I was thinking of using a AN T fitting in the line from the oil filter to the pressure feed line going back to the block I will use a check valve between the acumaltor and filter to keep oil pressure in the acumalator when sitting like you do
