Re: fuel pump
Pump has 5 second prime when ignition is switched on and then is powered continuously once engine is running.
Powered does not necessarily mean stroking... once the discharge line pressurises as a result of the floats closing the inlet needles then it stops until the pressure drops again. This is done by a mechanical mechanism in the back end of the pump.
