The first 2 sensors on your list are the same part, but only one came thru the VW network. Those sensors are the correct ones for 72-3 type 3s. All type 3 pressure sensors begin "311", the 022s are for type 4s or Porsche 914s. I had to look up the Bosch 007 one, there are too many Bosch numbers to memorize. That one turns out to be for a 70-1 type 3. > Can be that these sensors are for different cars but internally and > functionally are identical? They may look the same on the outside, but they are calibrated differently on the inside. Your #7 should have some slots in the cover which the E sensors don't have. Those have some additional parts inside as well. > Anyway what I really need is to have one spare sensor for my car and, if > what I found isn't good for my '72 car, sell what I have.

If it leaks, I'd still pay shipping to get it here. > What is the correct automatic transmission VACUUM UNIT number for my > car (body # 362 214 6881) ? 72-3 used the late vacuum modulator: 003 325 391C, which is marked with a brown paint stripe. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
