External oil pump pickup pan mod...?

There is a male fitting that screws into the stationary pick up, and you "can" put an o ring and washer on it, w/ the nut on the out sid4ew/ an o ring and washer underneath it . I DID, before pulling it on the engine stand , for the swinging pick up. Why, just cause I always wanted one.
Their are a few diff combinations that a guy can use.
Thank you for your input. Getting all the info I can to determine my best option.
