Review on Carter M4566 Mechanical Fuel Pump by Tim Duncan

This was not an exact replacement for the original fuel pump. The inlet and outlet were not in the same location on the pump housing as the original. In fact, they were in the opposite location on the pump housing. The fuel pressure generated by the new pump may have been too high as this caused fuel to leak through the carburetor top seal. It seems to me that the manufacturer is trying to make this pump too versatile. The good thing about a fuel pump is that it actually pumps fuel.
