Yesterday I had Xena running for about 5 mins without any leaks then she started dripping again.
This time instead of trying to repair the the rubber seal, I used a piece of inner tube to go over the entire spring.
After stripping down the new seal that I damaged I used some O rings to bond to the inside of the inner tube to create a water tight seal, my only problem was that the ceramic washer had a slight crack in it and although I sealed it plenty it wasn't good enough.
Any way after some pondering I stripped it all down into it's component parts, the seals are not made as one complete unit, there are two top hat rubber washers joined by a piece of tubing and the ceramic washer fits into one of the top had washers, so doing some googling I can get the individual pieces locally for literally pennies, knowing how these are put together has shown how simple they are to construct.
I haven't taken any photos but once I get sorted I will do an update on the new and improved seals to my specifications
