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!

must be a CA thing then?
but even then it might have been CA only for 70 cal. year.
CA has some special privileges doesn't it in relation to smog laws. they can introduce air pollution laws earlier than other states. recalled reading about it last year when former pres. trump proposed taking away the right and bringing CA into line with other states for uniform introduction of new laws.

its a pretty expensive set up for the can on the early cars (as well as 911s) as its two long runs of large diameter hose. VW were more penny pinching with their approach during the same era. only a long line of fuel vapor hose (small diam) to rear of cars and shorter lengths of woven hose from rear cans to fan and aircleaner. you can see why they changed it in 74 to a rear can. the accountants would have been doing the numbers looking for a dollar here and a dollar there. for the same reason they would have wanted to delete it from as many cars as they could early on in production.

the cars (4 or 6) that made it here in the 70s (all european spec) don't have any of it.
expansion tank or can. i think aus brought in the cans in 1975 following USA standards.
generally aus copied the usa about 5 years behind on just about all emissions stuff.
