Hate to tell you, but the large black-capped port is not the place. Neither the gauge for pressure testing nor the hose fit this port. Supposed to be a smaller blue-capped port, but cannot locate one on this vehicle (we have an F-150, a Freestar van and a Mustang besides the Expo so we are not Ford virgins).
