I have a 1993 Procraft 180 pro with a Mariner magnum 3 150hp (0D290081) on the back. I'm in the process of going through the entire boat. It has two fuel tanks with 2 sending units. The guage is erratic and I'm replacing all the gauges and need to replace the sending units. My problem is finding the OE sending units so they both can operate off the same gauge. When each tank is selected, it switches to that sender for the level. I'm not sure if any sender off the shelf will work... If so any suggestions?
