I recently replaced my fuel pump with OEM brand same as the original but the fuel gauge has erratic reading
or malfunction. And shut down the engine while on motion frequently. I gussed the technician didn't replaced the old connection to the sensor. If that could be one of the case. Or the Guel Gauge has rust or corrosion on the connection line I suspect. I hope some that has the same experiences can help resolve my vehicle problem. Everytime, I see a repair shop. They can hardly figure out. Thanks for any helpful infos... Wilfred
