Tin Tops car build, few questions

[dinger205]

Hi all,
I'm in the early stages of building a clio for tin tops, either BARC or CSCC and have afew questions, Most stuff is pretty straight forward and the blue book isnt the best for school drop outs, LOL,

My first question is about the fuel tank,
In the blue book it says it needs to be FIA approved, that means big bucks and when I was running stockhatch they would allow a ally single skin fuel tank under the car with the filler neck iside with a sealed flap over the top, is this the case for tintops?
My plan would be to have a cylindrical tank in the spare wheel well and seal this in with a cover.

Seats, simple one, do these need to be in date for BARC or CSCC? I have a really good seat and has only just expired but feel comfortable with it.

Many thanks
Dave

Thanks guys,

I'll be at the rockingham round of BARC tintops on the 6th of october so want to have a shifty around the paddock and have a chat with some people,

Fuel tank is plastic so may have to look into getting something made up if the plastic tank is not allowed,, If it is then I will have a swirl pot fitted with additional pump.

As soon as I posted about putting the tank in the wheel well I realised how stupid that would be so that plan has been scrapped due to the risk of being hit up the back or backwards into the wall.
