Just put on all new outside transom lines on 1979 Mirrage and not sure where to fill fluid and how to bleed?

I think you have a capilano helm in that. There should be a fill port on the dash that connects to the top of the helm. Attach a hose, can, or funnel to fill and make sure it stays full. Bleed ONE direction at a time the old fashion way: by turning helm and a second person loosens fittings at one ram then the other ram until solid fluid comes out . Repeat in opposite direction. If helm goes dry start all over again.

wow sounds like a PITA
