That changed from oval to round, along with a change in the venting scheme, in mid-'68. The venting change is shown in the Bentley manual. > Now, I find that the 1969 tank has a ROUND filler port, but does NOT > have the vent port on the other side. > So, I think I've found a tank that I can use although with a vented gas > cap.

VW introduced the Evaporative Emission Control system (charcoal cannister) in '70, so I think all the cars after that had tanks with slightly different venting ports. That's why I suggested a '70-3 tank as a replacement for a '71. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
