This is the second and third of those pumps I've used. I will continue to use them We tried replacing the gears in the first pump with a new set I keep in stock and then tried replacing the entire pump to identify the problem with another new one, the pumps or gears wasn't the problem I looked at trying to use the built in passage in the World Block for the second oil line but decided to not use that option due to the small hole and sharp bend in the oil passage in the block
