after the pipework that joins the fuel tank to the filler cap if anyone can help?

Fantastic, cheers mate

Just make sure before you buy that it is marked for fuel use on the hose or comes with compliance documentation.

I got mine from Merlin Motorsport (checked first to confirm theirs was marked for fuel use).
