Is it necessary to change the charcoal filter in the fuel system? MY 968 has 88,000 miles on it now?

if you are referring to the fuel filter in the rear, then yes, it should be changed at no more than 60k miles

The one on your car was changed before you bought it, I saw it with my own eyes...

You say you saw it changed? did you own my 968 before me?

The part I think I was referring to is called the Carbon Canister; Part number 993 201 221 01. In other cars it is referred to as a charcoal filter, not the fuel filter. I understand it traps fumes and has something to do with the emission's, but I might be wrong on that remark.

In some cars ( MBZs ) carbon filters are synonymous with cabin filters, not sure if Porsche uses the same terminology but I suppose it's a " canister " in this particular case..

jay saw the filter changed because the car used to belong to pete, and jay hung out at his shop.



the carbon canister is indeed up front, and as far as i know, does not need to be changed, though i have heard of at least one car that failed a smog test and had to change it.



dan - the cabin filters on this car are normal fiber filters, not carbon

I don't think I've ever had those changed ( and where the heck are they ? ) in the blue car, and have no idea about the new one .

Me too. I'm sure then mine must need changing if I haven't done them.

I don't think the early models have got a cabin filter. Not sure which ones do got one.

92-93 don't have cabin filters, In 94-95 the cabin fan housing design was changed slightly and adapted for cabin filters.

This is an example of where a discussion goes off point. I am NOT TALKING ABOUT CABIN FILTERS. Those are two small fiber filters that sit just in front of the windshield near the windshield motors. They look like a small 6 inch by 6 inch box of Kleenex. they are under a flimsy piece of plastic.. Turn on the cabin fan and it draws fresh clear air thru the filters into the cabin.



I am talking of a CANISTER FILTER clearly shown in the parts catalogue. In other cars it is normally called a charcoal filter. Porsche calls it a canister filter, I think.

correct. please see my post above, where i answered your question.
