Hi,
I've got a 90 degree 50mm elbow for fuel filling that MK gave me as a freebie. Its marked as a CH5090 which looks via t'interweb to be fine.

I've been told the IVA requires either labelling or evidence of compliance. Anyone know what they mean by this as I've not got a receipt, but I can dump info from a US website that sells them as fuel compliant.

Either that or can anyone recommend an alternative product that gets through the IVA?
