I binned the fuel distributor I was making, too big, and made another smaller one. The design has changed a little: There are outlet spigots either side of the fuel distributer this time which feed the carbs via fuel hoses, the two outlet spigots are joined by a 4.5mm through hole. A line from the petcock feeds into small plastic filters which feed into the two brass spigots on the front of the distributor, via fuel hose, and these feed into the 4.5mm through hole.
The brass spigots have been undercut on the face connecting to the distributor to allow for an O ring. The brass spigots are a push fit in the distributor so shouldn't leak, the O rings are just added insurance.
This was about as neat as I could make it and certainly neater than the jumble of hoses, adapters and T pieces I had there before.
I didn't bother polishing the ends, that was a mistake - looks unfinished, so I'll have to remove it and polish the ends.
Here's lots of pics (as usual), including the build process.
