Hi Alfons , If you look at my most recent postings you will see that Fans are quite high on my agenda at the moment as the one on my 500L has just broken and damaged my engine. I thought that a mild tune on a 499 ccs engine would not be a problem but it looks like it is if you push the engine a little over the standard revs. The hose clip /support was just a piece of buckled metal on the bottom of the tin ware . The previous owner of the engine & the guy who had the work done on the engine is quite a famous retired Test Pilot who also raced cars & motorbikes on the European circuits . When I first met him he showed me the Fiat Cinquecento cars that he had modified & used everyday. He does the work himself & one was running a 1.6 Punto DOHC Sporting engine. Not bad for a guy who had just had his 70th birthday. He is & was very much very much into experimentation & pushing boundaries . I am going to write to him soon to see if I can find out more about what he did with the engine [-/
