Review on Premium Module Assembly Compatible Mercedes Benz by Robert Hardin

2 pumps I received had quality issues. The first pump didn't work at all. The second time the pump was replaced, the float sensor in the package broke and after a couple of test rides, the engine started making noise. From the outside it looks like the original inside, the location of the fuel pump is shifted by 1 inch, which means that the fuel line must be tightened to connect it. it also makes closing and sealing the gas tank more difficult as the pump must be angled to the fuel line attachment point.
