Knocked this up a couple of issues ago and delighted to say it's working well ... except for the first time I ripped the aluminium jar off it's well-supported lid while putting the bike on the ramp: luckily that came as a set of six.

What I really need to do now is reseat the anti-siphon ball bearing so it's not needed as frequently - which will probably make a single page feature soon - but we all know that the best cure for 'sumping' is to ride the bike ... so I am.
