I’ve seen two versions, a red locking collar type with o-ring and a push fit but that may have been on a ZS180. Removing the sump is not easy with exhaust fitted, the corner set screw on the sump has to be cut in place with the sump dropped by approx 3/4” or so, use a hacksaw blade to cut the thread between the faces. Fit a slightly shorter set screw.
