Your setup looks good Andy I like the bulkhead fittings going down under the car, only two problems is one your losing your spare wheel well and some boot space.
My plan is to buy an aftermarket tank and fill it with this anti-surge foam, if it doesn’t work then I’ll have to bite the bull it and run a 2 pump swirl pot set up.

my only concern is the foam getting in the way of the fuel sender float, if I bought foam in large sqaure sheets I could stack them on top of each other and have a cutout for the fuel sender
