Bosch electric fuel pumps 73 911

[lyon]

After owning my 911 for 7 years and going through multiple rebuilt electric fuel pumps, I was wondering about solutions to alternative fuel pumps that might work on my vehicle.
Has anyone successfully installed a lower cost replacement pump?

My current pump works part of the time, but other times it freezes up and doesn't pump. Does anyone have the same experience of the pump nut running half the time? What was the solution to making it more dependable. It was rebuilt two years ago, doesn't leak, sometimes a good whack with a screwdriver gets it going.

On my 73 I moved mine to the front of the car, away from the heat, just in case that was killing them.

wayner - do you have any pics or a parts list of what you needed for that?

Information helps. From what I can find it is MFI. Have you made sure the tank is clean and flows properly. The fuel pumps are cooled and lubed by gas flowing through them. If you run it with a low tank or the lines or filters are clogged it will burn them out quickly.
I have a cis, and at 140,000 the original pump was still working. I don't think the heat from the rear location is as much of an issue as some think.
