S&B 86-3001 Fuel Sending Unit

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!
