Edited my last post above. 1 single pickup, the bolt on pump cover one.

Tests I read said that this pump "Cover Type" pickup with a standard volume pump will flow more oil than a stock pickup with a Melling high volume pump.
The stock pickup is a huge bottle neck. I have seen some that are thick tube outside but small inside diameter. The biggest inside diameter ones I have seen are 1/2 inch inside until 1 inch from the pump and then necked down to that 3/8s pipe screw in.
