Good evening all

I am attempting to replace my fuel pumps on my 560SEL. The issue I'm having is twice I've ordered new pumps off of Amazon. They are from two different vendors. Online the pumps show as a match/ fit for my car. The end of all of the pumps that the banjo both screws into is a different size on the fuel line vs. The actual threaded he on the pump.

The first vendor varied that the pumps I recieved are the proper replacement for my pumps #10580254950. I was told by the first vendor the banjo bolt and hole is 50mm and my bolt is 60mm.

What am I missing? How can I ensure the proper fit? Is there a work around? My old pumps have the smaller connection. Any assistance is appreciated.

Thank you

Ron

Do you have examples of all the pumps in hand? If so, put a card with a number next to each, and take pictures. Tell us which is which. Take pictures of the check valves, and of the banjos & caps.

There is nothing in the attaching parts that is 50 or 60 mm long, let alone in diameter. The check valves are about 40mm long overall, and have a 10mm thread on one end, and a 12mm thread on the other end

I'll get those pictures tomorrow. Thank you
