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.
