Finally just had the fuel fix done and I have filled twice and it works great
before that it was taking me 15 to 20 mins to get 20 or 30 litres in
I was away on a trip and the 1:30 position was not working at all.
Parts are as per Festa's post as I got them to give me a photocopy of the parts list.
