What happens when a fuel pump is not running?
When the pump is not running, the check valves on the pressure and return lines normally seal the tank from the lines. If either of the check valves start to leak, the tank with the leaking check valves will overfill when running on the other tank. The repair for this is to replace the fuel pump assembly.
How is the fuel pump connected to the front tank?
When you’re in “front tank mode” the selector switch sends 12 volts to power the electric fuel pump in the front tank. At the same time it connects the fuel gauge sending unit in the front tank to the fuel gauge in the instrument cluster. When you select the rear tank it does the opposite, and hooks up the pump and sending unit in the rear tank.

Can a gas tank be moved to the front of a boat?
My concern is that the fuel pump will not have enough power/draw to move the fuel that far. The boat is a 18′, I figure the run from the center of the boat (front 1/3) to the engine will be 14-16′ (+/-). The engine is a 140/105 Suzuki 4 Stroke Is there anything I should do or worry about tp move the tank forward?
