fuel filler neck

hi can anyone tell me if any kind of joint or seal goes between my new filler neck and the inner side of the rear wing on the flange with the 3 screw holes? it was already removed and nothing came with the new neck. many thanks.

Here's an exploded view of the top of the filler neck.  You can see what you have and what you need…..

thanks ew, i just have the neck itself none of the other stuff apart from 39 which is the decal to hide the screws i think. is the joint number 2 rubber? i have access to loads of jointing material so i could make that no probs. thanks again

No 2 is a foam gasket, no 8 and 31 are plastic filler neck surrounds, think 32 is a plastic splash guard. From what I recall what bits you need is down to whether it's a petrol or diesel.

Cheers
