I past post on this subject a cure to the problem is to raise the pick up line from the pan above the pump . this will hold oil some oil to prime the pump. On my system,I have the line from the pan going up almost to the header then down to the pump, never had a problem. Now have added a accumulator for pre-lube which would pre prime also .
