Gentlemen,
All fuel plumbing completed, had small strop when I found my pipe bender would not do 1/2 " od pipe so borrowed old small saucepan from wife filled with damp fine sand on put on low heat whilst stirring to dry sand. Took about five minutes. Filled tube and blocked both ends heat treated copper pipe and successfully bent tube around larger dia pipe.
Fuel tank has a leak to fix and fuel pump doesn't, something to do tomorrow. Water plumbing needs a couple of jobs otherwise nearly ready to run.
