What is a pump relay?
A pump relay acts like a switch that the controller can turn on to provide power to the pump. Since the controller outputs 24Volts AC power, and most pumps require anywhere from 110-220 Volts AC, the pump relay acts as a step-up transformer to route additional power to the pump and activate it.
What is a fuel relay?
The fuel pump relay sends a current to the electric fuel pump. A fuel pump relay is an electrical device much like an automotive fuse. … The relay operates as a monitor for the power going to the fuel pump, activates it when the ignition is turned on, and turns the pump off when the vehicle is turned off.
What fuse controls the fuel pump?
Replacing Fuel Pump Fuse Most fuel pumps will run a 15 (Blue) 20 (Yellow) or 25 (Clear) amp fuse. Using a fuse that’s too small will cause the fuse to blow again. This is a normal condition as the fuse isn’t rated for the higher amps of a fuel pump circuit.
