My 2010 E89 S30i stalled on me while driving on the highway, got it towed to my mechanic and he found out my fuel pump died on me. He suggested replacing the entire assembly but I opted on buying just the fuel pump, I bought the Pierburg replacement pump and I want to know where can I buy a replacement for the filter that’s attached to the pump itself, my mechanic said we could reuse the old filter but I want to replace it since the original pump died because of contamination build up.
