The S&B 86-3000 fuel sending unit fits 2005-2007 Dodge Ram 2500/3500 pickups with the 5.9L Cummins and 2007-2009 Dodge Ram 2500/3500 pickups with the 6.7L Cummins. An aftermarket lift pump moves more fuel than the factory setup, but on these trucks it commonly starts pulling air once the tank drops to about a quarter. That air means pump cavitation, falling fuel pressure and a truck you can't run low on fuel.

The S&B sending unit replaces the factory unit so the aftermarket pump can keep drawing fuel all the way down, letting you drive to empty. It is completely plug and play, with no modification to the OEM tank or sending unit. It is built for use with aftermarket lift pumps only. No core required.

Vehicle Fitment & Technical Installation Notes

Installation Tip: Run the tank as low as practical, disconnect the batteries and relieve fuel pressure before dropping the tank or removing the sender. Keep the tank opening covered so no debris falls in, seat the new seal evenly, and confirm the fuel gauge reads correctly and the connections are dry before the first drive.
