Raychem Fuel Pump and Fan Relay Assembly

The Raychem Relay Assembly is for ECU controlled fuel pump and fan activation. It eliminates the use of a dash mounted manual switch for the fan and fuel pump. 

***Important, you will need to purchase the 608-4192 ECU Pigtail separately as this is different for each ECU make.*** 

Using the ECU to control the fuel pump is much safer than a manual switch as the fuel pump will shut off automatically when the engine stops to prevent fuel from pumping out any broken lines or fittings as soon as possible. It also allows data extraction from the ECU without the fuel pump running the entire time. The Fan relay will automatically turn the fan on and off preventing the engine from overheating or running too cool.
