Driven Diesel Fuel Pump Controller kit 73FS-OBS-PumpHarness
If you are upgrading the fuel system on a 94-97 OBS Ford Powerstroke to include an electric fuel pump, you need something to properly control how it is operated. This wiring harness includes our OBS Fuel Pump Controller as well as an oil pressure switch to operate like the PCM controlled pump in the later Super Duty trucks. The controller is designed to run the fuel pump for 20 seconds at "key on" to get the fuel system primed. If the engine is started within that time, the oil pressure switch will keep the pump running. If the engine is not started within 20 seconds, the controller will shut the pump down so it doesn't stay running.
The pump controller has been upgraded to modern, surface mount technology components and circuit board, and the harness and relay upgraded to 40A components.
NOTE: IF YOU ARE ORDERING THE ABOVE HARNESS, YOU DO NOT NEED TO ORDER THE FUEL PUMP CONTROLLER AND PRESSURE SWITCH...THEY ARE ALREADY INCLUDED WITH THE ASSEMBLED "OBS" HARNESS!

Nice kit, makes converting to efuel a breeze on the wiring side. Truck now acts like it came factory with an electric fuel pump, and don�t have to worry about the pump running too long with the key on.

Works and fit great. Easy install. Great way to control electric fuel pump on an Obs 7.3.
