Metrum Rod FSU
The METRUM ROD Fuel Sending Unit (FSU).
It replaces the failure prone original style FSU wiper board. The original is exposed to the fuel and over time will deteriorate to the point it does not work. If your fuel level gauge is bouncing then the FSU is most likely the problem. It completely isolates the electronics away from the fuel and is plug and play for the 6.5 Diesel trucks, Suburbans and vans. Should also work on Cab & Chassis models.
Made from 316 stainless steel and installs into your factory or aftermarket FSU.
