I need the part number for the holding tank level sender. My mechanic ordered one and got a three wire plug. Mine has a four wire plug. The boat is a 2004 36 Mariner with a 20 gallon tank, later Mariners had a larger tank but the same height so I thin the sender is the same. Any helpwould be appreciated.

I have a Tankwatch III in my ‘96 355. Three tubes and 3 lights checks at 3 levels. You probably have a Tankwatch IIII which has 4 tubes.

We just replaced ours, with a Tank watch exterior sensors. Never again am I going to remove that sensor to clean!
