Sorry, it was a one of on ebay a couple of years ago and not a name supplier or I would remember. Well teed off that it appears not work as it's lovely and shiny. Posted on here asking if anyone knew how to test them as I would have thought there wasn't much to go wrong even if it had been lying on a shelf for twenty years? No answers forthcoming, plenty stuff on you tube but expensive to buy.
Looked at aftermarket ones with a gauge but looks a guddle making up new fuel lines to them.
