Duncan, I have a 'T' in thefuel linejust engine side of the confluence of my
two parallel arranged electrical pumps. This takes a short length of hose to
the pressure switch, all fixed to vertical ply support under baggage bay. It
has never flickered except when main ran dry x 2. With the 914 the fuel is
being driven through a pressure relief valve which may have something to do
with it. David
