I followed the recommendation of a friend who was a Porsche/Mercedes Benz mechanic and used a pierburg pump that had been used by Mercedes and Porsche in the 1960s. Eurocarb no longer sells this pump (perhaps because Pierburg pumps are no longer made by a German company). Mine has been in service for three years now.
I patterned by install after Steve's install, using the same location, similar isolation mounts, and the fuel pump relay with the engine (ignition coil current) cut off and the three second prime at start up.
Because fuel pumps often give no warning before they fail, I tried to do my install in a way that would allow for a relatively easy roadside change. I bought two identical pumps and wired them both with pigtails that fit into a connector wired to the car. The spare pump is stored in the car. I can change my pump with a 10mm wrench for the mounts, a screwdriver for the fuel hose clamps and a vice grips to hold off the fuel while I make the change.
Steve suggested recently the possibility of using marine quick fuel line disconnects. I had not thought of this, but if I had this to do again, I would strongly consider it.
