Top picture is of the main tank vents going in at last.  With a lot of trouble, I made 20% glass filled ptfe packing, but when I eventually fitted them in, the packing jammed the valve solid.  After a lot of poking around, I did away with it.  The important bit is the main seal in the through hull.  At first, I couldnt get the O rings to go in, it’s such a tight fit, so I drilled a slight taper into the entry and they slid in perfect.  I am using 3 x 8mm epdm O rings with silicone grease.
