injector copper washer question

Does it matter which direction it goes on? One side has the lip and other has the indent going around the middle of them. Sorry if its a dumb question.

Double lip down.

The instructions from Ford state orientation optional, but If dave prefers them installed a certain way, I wouldn't argue.

Double lip down.
