Hi everyone!
As I stated in my introduction, when I bought my 1985 K100RT, it had a dead fuel pump. I found that the Ford (late 80's Taurus I think) fuel pump will work. For those of you in the US, the NAPA part number is 2P74095 and the Advance Auto part number is E-2042. The ford pump has a smaller diameter than the BMW so it is recommended to build a 'spacer' with an oversized fuel line. I could not find big fuel lines like that so I used the gaskets that came with it and wrapped the fuel pump with then. I then jammed that whole thing into the fuel pump holder in the tank. I also used the fuel pump screen that came with the new pump. If you rotate the pump right, you can get it positioned into the metal pump holder thingi in the tank. You also have to change the leads on the wires in the tank.
Feel free to contact me if you have questions. My bike is in pieces at the moment for repainting so I could send pictures if you needed them.
