1970 911T Replacement Fuel Pump

Fuel System

Vehicle Information: Model: 911T; Year: 1970; Body Type: Coupe; Engine (type, size, modifications): 2.2; Total Mileage: over 100,000;

The electric fuel pump on my 1970 911T appears to be giving problems. Initially the car would start and run for some distance (a few miles) and then seem to run out of gas. After a short rest, the car could be started without adding gas to the tank and would continue and repeat the same out of gas routine. To try to troubleshoot the problem, I have continued to drive it on short runs. The intervals between the out of gas situations have shortened (one mile tops) and the fuel pump seems to have a weaker than usual sound when this happens. I owned an MGB once (temporary insanity) that acted the same and I eventually replaced the pump. The pump has no name on it, but has the Bosch symbol and appears to be stock. The mounting and wiring also appear to be stock. The pump has a larger (3/8 inch) inlet line from the tank, a smaller (5/16 inch) outlet to the carbs, and a similar size reserve (or return) line that comes from a lower point in the tank than the inlet. I have been told that these Bosch electric pumps are no longer available. Most replacement electric pumps I have seen only have an inlet and outlet. What type replacement pump should I use and is there one that will plug in and/or mount without modifications to the current setup? Any help you can give would be greatly appreciated!
