One of our own sent me this one which does not have a diaphragm or even a place for a diaphragm! (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Attached image(s)

The aneroid cell has a fixed threaded allen key adjustment whcih only gives 0.004 Inductance adjustment, not sufficient for our needs.

They were really learning with this setup, and changed it fairly substantially each year until '71, when they seemed to get it about right. I have a '69 Squareback, and the system is similar to, but still quite different from, the 914 D-Jet. The '71 Type 3 system is very like the 914 setup.

I bought it off of ebay a few years ago thinking it could be used for a D-Jet 914 but the hose connections are quite a bit smaller than the ones for a 914. Angled slightly different too. Part Number 0 280 140 005 or VW Part Number 311 906 045 Attached image(s)

The T3 part number should give you a clue ....................... The Cap'n

The '68-'69 AAR was very different, as it used oil temp to close and wasn't electrically heated. That may, in fact, be the unit for the Type 3 automatic, which used a different AAR than the manual cars.

Ernie made me do it! Group: Benefactors Posts: 2,312 Joined: 6-February 03 From: Pleasanton, CA Member No.: 257	Jeff When I bought my car, it came with that exact same MPS. It was tweaked to run with a 2056. I never took it apart and never knew that it didn't have a diaphragm. I always had wondered why there was only the one adjustment screw in the end. Anyway, my engine ran great with it for many years until I started fiddling with other MPS's and custom tuned one for my engine. I have the inductance curve for it somewhere in my files. Anyway, interesting that you took it apart and found that it is quite different inside from the type used on our motors. Demick

It's a Type 3 part, so sell it to a Type 3 owner. The Samba has thousands of them, and they have the same MPS problems we do as far as availability and reliability.
