1982 380 Sl Fuel Pump replacement

[NewmanP]

I am looking to rebuild my fuel pump. My Question's are this

1.I bought a new Fuel Accumulator . But when I went to install it the fuel line nut is to small and will not start on the threads to the Accumulator. Part number is 000-476-04-21. The Fuel line is out of a 560 SL

2. Will a fuel pump from a 560 sl work on my 380 sl. The Fuel pump that I have is a new one Part # is Bosch 0 580 -254 950

3. The Fuel filter that I have is Part# 002 477 44 01 this also came out of a 560 sl
will this work or will I have to replace it with 002 447 17 01

Thanks for all your help
