seem to remember reading somewhere that you might have to fit a restrictor in the neck of some fillers but can't appear to find any reference to it in sva manual, any info appreciated it's a blade so I guess it's unleaded , nozzle sizes etc
Many Thanks

its 23.6mm max diameter hole,i found a washer that fitted the bill but it wasnt checked

You can get these from think automotive. You only need one if you are using a cat for SVA.
