Ferrari Mailing List: Re: Carbs, fire and costs

[cmlf1 (cmlf1]

I had a SAAB 900 turbo with CIS. I recall doing major servicing on the engine 
and slightly moving the CIS injection lines would result in them breaking, so I 
naturally replaced them all with new. They should be replaced at an interval as 
once the plastic hardens they are a fire hazard. I think some MB models used 
steel braised lines as opposed the the fragile plastic.
