70 to 71 differences

[cbudvet]

Hi there, first time user. I have an early production 70 240z that I am trying to restore. I recently purchased an early 71 to use for parts etc. When I look at the gas tank / fuel filler area they are very different. The 71 has a vapor tank and a lot of extra hoses associated with the gas tank that the 70 does not. Was there a major change between the first and second year? Thanks.

Welcome to the club.

I'm afraid you'll find that changes were introduced constantly, not just a "model year" at a time. There were a number of features unique to the earliest cars. Fortunately there are quite a few people here who are quite knowledgeable in this area. I suggest that you update your member profile to include your location as well as post your VIN (HLS30-#####) here so that people can help in your quest.

"The Early" cars didn't have evap tanks.....The gas tank also lacked the vent on left side as well.

"The Early" cars as far as evap tanks go what I know is at least first 2400 or so cars didn't have evap tanks....In the United States. VIN # 333 is thr car in question....

I hope some others will chime in to clarify.

While you'll get a lot of information here, check: www.zhome.com where you'll find a list that breaks down many of the MAJOR changes according to year and where possible, gets it close to VIN #.

However, be aware that that list is very U.S. Market specific and that variations existed amongst different markets as well. That is, "European" Z's had different options and features that weren't readily available in the U.S.. There were many owners that would seek out those parts to personalize their vehicle also.

Hey guys, I have #2562 and it appears to have come from the factory with no evap tank. The fuel tank has no vents and the hard line that goes to the engine compartment for vapor recovery is not there either.

Hey there 333. I just shot off an e-maill to 332. Welcome to the low VIN club. Although it is true your car was registered and titled as a 1970 model year, your car was built in 1969 - November? Check the ID plate on your door jamb.

This is a great site for pictures of peculiarities concerning the early cars. http://www.geocities.jp/datsunz903/ A search through the archives here (search "date stamp") will lead you to a number of threads concerning dates of manufacture and various other idiosyncracies concerning the early cars. Yes, you have a unique car. No, you don't have a fuel vapor recovery system. Take good care of that gas tank. You are not going to find another one like it very easily. Best of luck with your restoration. Let me know if you need parts.

Interseting.....My 1970 (s/n 02126) does have the evaporation tank and vent lines. Man, imagine the things that took place on the assembly line for the production of the early Zs......"well, partner-san, what changes do we have today?"LOL

I am starting to wonder if my car is not an import from Canada, the dash was changed out like in the 90's and the numbers matching engine does not have a vapor recovery nipple on the crankcase breather.

The filler neck has only the one "t" fitting on the big vent line that goes down through the inner fender.

A little off topic....but does anyone know if the Canada cars had Km/H speedos? That would explain the incorrect interments in my car/

Thanks,

Eric

Eric - Canadian 240Z speedos were in miles/hour. We only went to the metric side in the late 70's (77/78ish).
