1968 Porsche 911 Hardi fuel pump test after repairs

After re-surfacing critical valve face and chamber sealing surfaces, cleaning and polishing the dual electric contact point faces, and adjusting the diaphragm pull rod for correct point "Throw-over" operation --the pump works great. We await now only a new condenser that will help to eliminate contact point arcing and metal transfer that was evident on the points prior to cleaning- for the long run. The video does NOT show that I pinched the output line to restrict flow and prove the pressure readings simulating the carburetor float valves had shut, or restricted flow. Sorry, it was out of screen view.
