Tachometric Fuel Shutoff Relay.

This type of relay is used as a safety device. If the vehicle is involved in an accident where the fuel line is fractured, the engine will stop due to lack of fuel BUT the fuel pump could continue to operate.

The TFSR monitors a coil negative or ECU signal and switches off the fuel pump when the frequency disappears.
