Fuel tanks baffle plates in gt40

Hi all,
what size ,and where have you holes in the baffle plates-compartment to let the fuel move from one to another compartment?
10mm hole(s)in the bottom? ..... one hole... more...?
15mm hole(s) towards the top of the tank?
at the end of both tanks their will be a baffle plate with one-way trap door to let the fuel in.
let me know your ideas please
Thanks
Paul

Greetings Paul,
The photo below illustrates one of our bladder set-ups before we switched to aluminium tanks.
The internals of the new tanks are pretty much the same as the bladder ones.
Your foam should prevent much of the surge but a baffle before the fuel gauge sender is maybe a good idea in case your foam moves.(see the two parts which look like paddles, these are huck riveted to the oval top plate)
The top collector box near the old pumps has an internal pitot tube bending down to the bottom of the box.
If you need more info just email me as usual.
All the best,
