Fuel Sending Unit (For use with aftermarket lift pumps) for 2013-18, 2021-2024 Dodge/RAM 2500 3500 6.7L Cummins - S&B Filters - 86-3001

Aftermarket lift pumps provide more fuel to your diesel engine but face issues at a 1/4 tank fuel level. The S&B Sending Unit allows you to drive to empty with your pump. Completely plug and play, with no need to modify your OEM tank or sending unit.

*For use with aftermarket lift pumps only.
DRIVE TO EMPTY. NO MORE LOW FUEL LEVEL ISSUES.
The S&B Sending Unit uses a Venturi Jet Pump powered by your aftermarket external lift pump to keep the reservoir full, even with extremely low fuel levels in the tank. A full reservoir means fuel to your engine and no check engine lights!
