Review on High-performance QFS OEM Inline EFI Fuel Pump Replacement for Mercedes-Benz/Audi/Volkswagen/BMW/Ferrari - Replaces E7127M, 431906091D, 0580254942 by Mike Sutherland

I replaced the fuel pumps on a 1987 Mercedes Benz 300E. They worked great. More durable than OEM. Good value for money. Almost 50% less than some well-known brands. The pump diameter is slightly larger than the OEM, but you can install them with heavy duty cable ties instead of a screw. My car has two, so I swapped them both. It's much easier to get the entire assembly out from under the car (if your car is securely jacked up) and work on it on a workbench.
