Hi Ian,

Thanks for this. I was tipped off that it was one of yours and I've just 
been reading it - nice work. It answers my question of how to accurately 
monitor fuel flow with a return line and just one transducer - although 
the required plumbing does leave the connections to the carburettors 
exposed to possible vapour lock (as Nev pointed out).  As with all 
things in aviation - everything is a compromise.
