87manche Posted January 13, 2007 Share Posted January 13, 2007 fuel pump ballast resistor. you can jumper from one side of it to the other to make the truck run, the pump will ust be a bit louder. Link to comment Share on other sites More sharing options...
comancheman Posted January 13, 2007 Share Posted January 13, 2007 its a resistor. i guess it makes the fuel pump run quieter. Link to comment Share on other sites More sharing options...
mike Posted January 14, 2007 Share Posted January 14, 2007 since it's a resistor it cuts down on the voltage going to the pump which makes it run slower, thats why it's quiet. jump the resistor and the pump will get full volts and run at max rpm thats why it's louder. i bet the pump will wear out faster though running at max, but i'm sure it'll be ok to do that for a short period of time, like for example to make it back home.
