I always try to soak a drop of light oil into the trigger point pivots whenever I have them out, and this generally seems to keep things free. Mercedes had a few D-jetronic cars and some of them also had this problem. They actually instituted a fix which consisted of drilling a very small hole in the side of the center stub of the pressure regulator. You were supposed to do this thru the inlet pipe/side port. The object was to give gas a way to flow BACK into the fuel ring after the engine started to cool back down, so that a vacuum could never develop in there and draw in air. The hole would make the pressure in the ring drop to zero when you shut down the engine, but that shouldn't cause a problem. The hole would bypass some extra fuel around the pressure regulator valve, but the fuel pump should have enough capacity to still handle that. I've never actually done this, however. I think I'd want to make a pilot for the drill bit and I'd want to use about a 1/64" bit. I think this would be hard to do without breaking the drill bit. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
