I have an '89 300e that the fuel pumps are going out. I have been looking around for them, and noticed there are a lot selling the pump for a single pump setup. Is there a difference between pumps in a single pump setup and a dual pump setup?

 

Please don't do what I did and buy 2 pumps for $200 from some cowboy in the USA. Both leaked and I had to replace them with original spec. Bosch ones, sourced locally.

I understand that Pierburg may be good too.

Just find the correct numbers and return your car to reliable working order.

The moral of my story is this, "If $200 for both looks too good to be true, it is!"
