1970/4 Build date 01/70 v.i.n. 4702903114.....no canister.
Pat, the "duh" was for me. All these years what I've considered part of the gas tank is really an.....expansion tank. Jeff, I hope you didn't take offense at my "duh", that "duh' was intended for me. (IMG:style_emoticons/default/busted.gif) Pat, it's good to see you moderating, keeping us all civil, informed and polite. (IMG:style_emoticons/default/clap56.gif) |

We are good Paul...I had only posted what I did because of your post that hinted of not understanding that expansion tank. I had posted the diagram earlier in the thread ID-ing the parts of the emission system.

OK, we're all over the map with with the VIN's & who had/didn't have the sytem.
Let's try date of final assembly - it's on you drivers side door jamb(rear). It's apparent that the late '70 cars had the system, but where is the break point? Sir Andy - you're out - later car & you had the system. Naberhaus (paul) - you're out - early car & you didn't have it. Crazyhippy (whatever that is) - you DO have it. Though your's is sorta mid-late, you have the sysytem. So, who's earlier than Crazyhippy (whatever that is) & HAS the sysytem? |

OK, here's more info to support my theory. To those who have a copy, check the April, 1970 issue of Road & Track that tests the 914/4. Again, this is APRIL, 1970. The picture shows a photo of a canister in a VERY EARLY 914. This car would have had to been tested in January, 1970 to make the April issue if not sooner. Road & Track is/was published in CA, correct? This was the press car for the CA market.
Also, 1971 was a big change in EPA emissions for all mfr's. All 4's at least required the cannister throughout the country. Maybe the '71 sixes did too. Don |

QUOTE(sixerdon @ Oct 26 2006, 06:24 PM) To answer DaveP's question, the small hose that would have vented into the filter, vents instead to a "Y" fitting on the large overflow drain line on the opposite side of the expansion tank. Don Exactly! There is also a second hose that connects the filler neck to the expansion tank. Going thru my 914 parts book also correlates with Pat's post that there were USA cars that did not have the evaporative canister(I take that to mean the charcoal element) system. |

Bleyseng's 4702909639 is so far the earliest to have the canister & all the rest. What was the build date? As promised, attached is the page from my parts manual that shows the variations. Interestingly, there MAY be a 3rd variant! Looks like there may have been a bolt, c clip & grommet to close the expansion tank off completely. Take a look & tell me what you think.

Parts 16-17-18? Those fasten the exp tank to the fuel tank bracket. There is another fastener on the the far side of the exp tank.

QUOTE(sixerdon @ Oct 26 2006, 06:24 PM) OK guys, I'm jumping in on this one. I have to side with Paul on his early Jan '70 car. I also have a Jan '70 car, but it's a six. Also canary yellow. My car was sold to the first owner in Lawrence, MA. It does not have the charcoal filter. Never did. It IS an American import. To answer DaveP's question, the small hose that would have vented into the filter, vents instead to a "Y" fitting on the large overflow drain line on the opposite side of the expansion tank. My other six, (March '70) has the full charcoal set up so I can compare the differences. I can assure you all, my cars are original in this matter. Paul, check the inner fender bulkhead under where the antenna would go to see if you have to holes. These holes would be for the 2 plastic lines going into the fender well and dropping to pass through and under the rear of the well wall. ie, you should have 4 holes in your fender well if your car has the filter. If you don't understand me, then look at a later car that does have it. Pat, if you want to help Paul achieve correctness in his restoration, keep an open mind with these early variations. Don (IMG:style_emoticons/default/agree.gif) (IMG:style_emoticons/default/agree.gif) (IMG:style_emoticons/default/agree.gif) (IMG:style_emoticons/default/agree.gif) BTW::::WHAT ARE THE VIN NUMBERS?? |

They did move to the engine compartment later on. My recollection is that is was on all 914 US cars, regardless of placement. Pat: My '70 914-4 does not have a charcoal canister, but does have the expansion tank around the fill spout. The '70 914-6 (Euro) does not have either. I should add, '70 914-4 VIN #4702907023 and '70 914-6 VIN #9140431113. |

Checked it on mine....found a smudge on one of them! Jeez, how'd I miss that? BTW, parts 24 & 25 are listed as "gummipuffer"s. Would make a great tech quiz tiebreaker! |

This has gotten VERY confusing! Why? Look at the VIN's that have responded so far (through 10/31):
Sixes: 0310, 1113, 1688 - no canister. Fours: 03114, 06783, 07023 - no canister 02960, 09639, 12181 - canister It all sort of made sense, except 02960 (which we have a photo of). I'm confoosed! |

I think CA vs ROW (or ROUS) must be the answer.
