Rowland Hi
why not have a purpose made fuel manifold =2C mounted between and below bot
h carbs with ports drilled for various takeoffs. So you can bring the fuel
in at the front with outlets to carbs left and right the return line at t
he top and the fuel pressure sensor mounted at the bottom . Eliminating the
tee pieces for a really neat job. The manifold could be made from a bloc
k of aluminium ect. Bar stock 30mm dia. and machined on the lathe.
Best regards Philip George

takeoff tee are (a) between pump & stbd carb=2C (b) between the 2 carbs=2C
and (c) between the port carb and the restrictor.
