S&B 86-1000 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.

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!

There is no need to modify your OEM tank or sending unit, so you can keep them intact and completely stock. Make easy connections with the OEM fuel quick connectors in the kit to install the S&B Sending Unit in your stock or S&B Tank.

The S&B Sending Unit has been tested in a wide range of low fuel level scenarios and is made out of OEM materials that are designed to withstand an aggressive fuel environment.
