Volkswagen Repair: VW Fuel Pump, wolfsburg west, spring cap

Question
Hi Gerald.
I am trying to solve a problem with my engine as my mechanic has given up on it and told me I have to solve it myself.
I own a 1966 bug with a 1600 air cool, and I know you specialize in the newer diesels, but my question should apply to your range of expertise as well.
My problem: Engine stalls once hot. Once stalled, engine will not start for several minutes (15-60 minutes). Problem increasing lately. Fuel filter sometimes empty during stall.
My attempts to solve: Replaced wire set, replaced spark plugs, replaced coil, checked points, checked distributor timing, tried adjusting carburetor, checked valves/oil change and now... Fuel pump rebuild.
I ordered a fuel pump rebuild kit (for 13-1600cc slip fittings) from wolfsburg west, trusting their quality, and a box with the a kit came in a funny looking "industria brasileira" box without instructions or a diagram. With extreme care I took everything apart and put it back together but my main question is this, and excuse the fact that I do not know the names of the parts in question. The rod that comes out of the engine pushes a pivoting part. On the other side of the pivot is a spring loaded small rod with a black plastic cap to the spring, and below it a plastic washer, and below it a metal washer, followed below with an even smaller washer welded to the bottom of the rod. Where does the pivoting part slip into this assembly? At the  moment I have it slid in between the plastic washer and the spring cap.
Any help you can provide would be greatly appreciated. You appear to be the only vw expert on the site and although you don't specialize in 1600 air cooled engines, it seems you are my best bet to solving my issue. I have not been able to find any diagrams or detailed instructions online.

Answer
Dan,
  The best advice I can give you is to go to your local library and access a motor's manual (import) for the 60's models.  You will find a section in the VW portion of the manual that will show a blow-up of the mechanical fuel pump...It may even have a section on rebuilding the pump.  You also have an option of putting an electric fuel pump on the system and bypassing the mechanical pump altogether.  Having said that, your problem may reside in a "vapor lock".  Early gas engines were sometimes prone to the problem (in warm weather/heavy traffic/gridlock conditions).  Hope this helps.  Jerry
