Why I Believe a Mercruiser 5.7 Electric Fuel Pump is Necessary

As a boat owner and avid boating enthusiast, I have come to appreciate the importance of a reliable and efficient fuel system in my vessel. And when it comes to powering my Mercruiser 5.7 engine, I firmly believe that having an electric fuel pump is an absolute necessity.
