Removing the old door: Take the pump case off before removing the rubber door. Grip the door firmly where it attaches to the pump and pull to remove.
Installing a new door: Push the pointed tab into the hole until you feel a snap.
Tip to preserve the USB rubber door: The rubber door swivels 360 degrees around the hole. While charging, make sure you are swiveling the cover rather than bending it backwards to preserve the cover.
