Over Flow Tank and Charcoal Canister 914-6 Options

[Mike Fitton]

I have researched on this forum for a couple of days trying to figure out if the 914-6 came with an expansion tank and charcoal canister, I do not have either on my '70 # 2604. My 6 has the brackets for the expansion tank so that seems logical but I have seen a lot of posts saying the 6's did not have a canister, does anyone have an original 6 that could comment on this. Thanks!

Since the recovery system is an EPA requirement, whatever the smog / emissions requirement for 1970 would have dictated which vehicle had the tank, filter system. .
I know Calif required them, but what about other states? I do know the
emissions sticker on the fan shroud states the motors comply with New York requirements, anyway mine does.

Well, related from a 914/6 question would be.. did the 911's have them as well for 1970? Did they have them as early as 1969? If so, then then the whole Porsche lineup would have had them for 1970.

However, if this was a reaction to the US passing the Clean Air Act in 1970, then it would make sense it could have been a midyear improvement, and conceivable a dealer "retro- active" installed requirement for later cars that sat on the lot? Just a thought.

I also imagine it was quite popular back then to remove "emissions" related things.. in the name of better performance and finding cars that haven't been "molested" for 47 years isn't easy...
