I am also considering if I can just replace the pump in the rear to keep it running for the rest of the summer and then take my time during the winter to replace the lines and move the pump.
Captain Krusty posted this on another forum several years ago in response to another person:
"Have you considered changing over (you'll notice I didn't use the evil word "upgrade") to a later model single inlet-single outlet pump? It fits the original bracket ans requires a different fuel filter, a short piece of 12mm hose, and a piece of 7/7.5 mm hose to put in place of the "Y" in the return line. Simple, effective, and relatively inexpensive. I cal talk you through it, if you'd like. Bosch #69 469."
I am going to PM him to take a look at this thread and offer any insight.

OK. Mount the pump in the original location. You're gonna need some 12mm hose, one of the adapter hoses from Porsche, and a short piece of 7 or 7.5mm hp fuel hose. The fit is tight in there because the inlet and outlet fittings are on opposite ends and there's not a lot of room under there. By enough 12mm hose to make a loop if you have to. If the new pump has posts for the wires, cut the positive and negative wires an inch or so from the plug housing and crimp on some good quality eyelet connectors. I use non-insulated versions and heat shrink where needed. If it has spade lugs, pry the securing tabs back in the plug and pull the female connectors out. Connect them to the new pump.
For the plumbing: Adapter hose to the filter, outlet hose (12mm) from the filter to the inlet of the pump, pump to the hose to the right side of the engine. The hose that was connected to the "Y" gets connected to the return line, using your new piece of HP FI hose. Done.
If you're gonna move the pump, ask Chris Foley about the plumbing requirements and run a new positive wire from the original FP wiring to the front and make a short ground wire to somewhere convenient in the front. Splice with a good quality butt connector and shrink tubing, don't solder. Better connection, better current flow.
