I bought a dual output manual TAP advertised for a Kawasaki for about 20 quid (maybe less) in spite of reservations it works fine. Screw on spigot type as above..

Thanks.l brought two of these years ago but I'm after the original look for a restoration and it's fun having a problem and successfully solving it.

When I purchased my T500, it had a gravity fed petcock and I noticed the vacuum line on the carb. I thought it was odd but found out that the petcock worked great. Here is a link of one that I found on fleabay https://www.ebay.com/itm/Fuel-Valve-Pet ... 1438.l2649
