Fuel Pump Codes And Control: Keeping Pressure In The Zone
The first electric fuel pump circuits were very simple. The pump circuit usually involved a relay and fuse. The control side to the relay was typically wired to an ignition circuit or key switch. The control of the fuel pressure was performed with an analog regulator that could keep a static pressure and adjust for loads with a vacuum signal.
