Fuel Filler Cap

[Davidbolam]

I am on the look out for a fuel filler cap for my build. If I am not using a cat on my build do I need to use an unleaded insert? I have found a nice one on ebay from Rally Design but it hasn't got an insert and they dont sell one.

No you don't need an unleaded insert.
I believe that was a requirement for SVA and has never been needed for IVA.
